Recently, the profession of a programmer is gaining great popularity. It also happens that people who die as programmers never start learning once they know where they are going.

There are no alternatives to an expensive endeavor. Today I will learn how to learn programming in the home minds and what is the best way to get started.

You can go through this process on your own. There are plenty of ways to do this. It doesn’t matter at all what programming you know in your home; you can learn it from scratch, at home. Having developed your profession. I would like to say that this is a highly paid and in-demand profession.

It’s important to get to the beginning, and even the programmer’s salary will remain in his knowledge.

How to learn to program from scratch at home

Well, the programming goes like this:

  • Web programmer (website creation);
  • application programmer (written programs);
  • System programmer (development of drivers, creation of OS programs).

First of all, let’s get started, find out for yourself what you need for whatever purpose you have in mind. Because programming is different. Think about what you would like to do: write games; Explore websites and work with financial programs.

There are a great number of our programs and their uses for song stagnation. The programming itself is divided into different categories. It is very important to begin learning the skills that you need to master.

For programming, English plays an important role. So start this and gradually complete it.

Today you can easily find services that will help you learn programming online. With their help, you can master the basic principles of robotic programming and create programs yourself.

Popular online services for basic programming

Let's talk in more detail about the most popular online programming services.

This service was created for children. Navchannya is awkward, but the process is long. The supplement is paid - it's expensive.

Why should you start programming?

We'll try to get started little by little to start programming from scratch in our home minds.

  1. Please note that you need to program;

Our programming, as you know, will remain at your peak at the right time.

  1. Choose the correct language;

The program does not have and cannot have good language. If you would like to learn one, then the decision will be much simpler.

Please note that the language is programmed, as it is quite difficult to learn for beginners.

You can use Python first to vibrate. The program code is suitable for the most important person. And the library base is good, and you can obviously save a lot of time.

  • Java is also suitable for beginners. This language strives for great popularity, not being surprised by those who are not so simple;
  • PHP is a simple language. You can easily find answers to all questions on the forum;
  • And the axis of the movement Ci C# of the newbies will be easy to install;
  • The Ruby language is good for another language;
  • JavaScript is an easy language, but there is not much behind it.

How to learn to program - start with the simplest, gain patience

  1. Get started with the program for children

Today, young children are starting to program. For this purpose there are special additions that are suitable for everyone.

  1. Take online trainings and online courses

Such trainings and courses will help you create your own program, and also allow you to learn about the basics of programming.

  1. Read programmed books

The evidence will miraculously help in the search for evidence in any way. On the Internet there are no books from programming.

  1. Play and play

Chantly, this is the simplest way to learn programming. You don’t just create a program, but you’ll have a fun hour.

  1. Find a mentor or become one

As you master the information, a mentor will help you, who will answer all your questions. You can find a mentor on a special website http://hackpledge.org/. In addition, you yourself can play the role of a mentor.

  1. Read the code of another customer

Try to rewrite the prepared code by inserting the skin sign. In this manner you will check him for mercy. Continue reading and learning something new.

If you have run out of food after starting programming from scratch, write to the popular forum - CyberForum.ru. The forum has a lot of sections from our previous programming. Give any nutrition and choose wisely, naturally.

Although the profession of a programmer is important, it is highly paid. Golovne zumіti muse yourself to read, try and figure out. I hope that the article helped you to learn how to program from scratch at home. Monitor your computer and protect your eyes. Pursue your goals, no matter what.

I hope that after reading this article you will find your way, and we will figure it out for you right now!

First of all, you need to decide on what you most want to achieve - create a website, write a program or develop a database for the specific types of finance. To be identified with the mark is the first stage on the road to great glory. By focusing on this specifically, you will be much more comfortable riding the horse of knowledge. Even if the world is programmed, the concept is even more complex, so you will have to learn about this world, losing your knowledge. Further, if you need it, you can easily move on to other spheres of activity, because the sphere in which you began to build your path will immediately appear in your entire life path.

If you want to create a great website, then you should learn about web programming. And if you don’t like programming as much as, say, modeling 3D objects, then the lessons of this are right up your alley. Nina has free access to millions of terabytes of useful information, lessons and courses from various universities around the world. Even quite recently, in order to be at the top of the evolution, we absolutely needed to start with the greatest initial deposits, where valuable knowledge was still there. And now let's go...

It should be noted that the knowledge of such sciences as mathematics, that English language, not necessarily, and you will soon understand how you will start writing your first program. Of course, if you plan to work on great projects, on GTAV, Cinema4D or Google.Maps, then such sciences are better to know. True, here evidence will help you more, which Swedish term will form your knowledge of the exact sciences. However, it is not obvious that there are certain areas of activity, such as, for example, neural networks, which simply cannot be done without advanced knowledge of mathematics. Just not the web, games, programs, design, etc. is up to your liking. In the first couples, you can do the process without bothering.

Before speaking, many people think that it is necessary to read your program, starting with the first language that appeared, and ending with the rest. This is based on algorithms, old languages ​​like Pascal, Delphi and others. Ale tse neobo'yazkovo. I would like to benefit from the fact that you will be able to learn them from the very beginning, with logical knowledge that you can then use when prompted to use modern language that is more accessible to a simple student. But you still need to start with language, since your favorite sphere is the most pressing, so it will help you quickly get comfortable and start making real money from it. And we can just teach you the basics thoroughly. In addition, if you just write the code a little, Swidko’s theory will become understandable and accessible, however.

First of all, it’s C++ itself. Before that, I didn’t know anything, and, trust me, everything fell into place. Later I entered the university. There we were taught all the basics, but I didn’t particularly study the sense in this.

Now let's take a look at the skin area. Let's get started with web programming.

Web programming

This area of ​​activity is one of the simplest and most accessible. Literally two months at a time is enough to transform from a complete beginner to a professional web crafter. Making money on this matter does not pose any special difficulties, since freelancing is a direct route between sea and mountain.

To become a web programmer, you need to know such programming and markup as (and along with it libraries, AngularJS and many others). In addition, you must write functionality for the site that you can write mine. You also need to consider working with databases and SQL databases. For a link to the database site, you can click on it. I’ll just stay to give you a couple of points of knowledge, that’s it. It allows you to make changes to the site, for example, adding data to the database without re-engaging the site itself.

So, Vivchiti will have a lot of new things. All you need is basic knowledge, without which this craft simply cannot do. Because you are attracted to this area of ​​activity, raise your outlook a little more and start taking everything into account.

Independent development of igors

This is one of the most complex, incredibly complex, complex and cosmically gambling areas of activity. Having started once, then it will be important to continue. Here it’s complicated and simple at the same time, and the complexity is compensated by interest. If you are building a game on ready-made engines, then you won’t see any problems on the horizon. And experimenting with what you create is the whole topic.

It is important to understand that the game can be played either with the help of various engines or by yourself. The difference is that the independent development of the necessary tools for the creation of a new game will require a large supply of terpine, which makes it even more difficult.

For example, to develop games on Android, you need to know the language and special libraries that are used to create games on Android in Android Studio.

To create games on a PC or console, you definitely need a language and all sorts of libraries that will help you create a game. To develop on IOS you will need the Objective language with or Swift, and you will also need the XCode program.

Development of games for additional engines

If you wanted to engage in the development of igors for the help of engines, then you are on the right path. Most games nowadays are created with the help of all kinds of game engines, which can include such giants as Cry Engine, Unreal Engine, Frostbite Engine, Dunia Engine, Source and so on.


Designer

When designing, you need to take good care of painting in Photoshop and 3D modeling programs, on the Cinema 4D platform. Two years of learning are entirely enough to determine the truth.

That's all. I have tried information about all the subtle skin areas of programming and information that you know you need to get rid of them. Fold those on kshtalt II ( Piece intelligence) I am on my side, because such knowledge is not for beginners, for whom this article was insured.

Well, you understand that the time has come to change your field of activity and learn a new profession. Why not try programming? It’s good to pay for something, it’s promising and it’s worth it. It’s all about nutrition: what to do, where to go, how to start programming? As a person who has gone through this journey from scratch, I can tell you that with the right approach to learning, patience and perseverance, you can easily become a programmer and find a job that pays well. With this article I want to share my pleasures as I publish the program.

Let's put a meta

To understand what to do and what to achieve, give me a simple answer - what’s next for you in programming? If your goal is to become a professional and earn money for a living, prepare yourself for serious and intensive preparation. If so, be prepared to begin programming immediately. If your goal is to broaden your horizons, you can choose a faster pace if you have a good time. But this time it’s not good to stretch out the habit “for fate.” First of all, knowledge goes faster and accumulates faster, but in another way, programming technologies are developing even faster. While you are developing a development tool or framework, it may become outdated and become unnecessary until it is ready. It’s best to make a rough plan for what I’m going to do. For starters, it’s all about the technology stack.

Choose a language

If you have a specific idea of ​​what you would like to do in the program, then it will definitely make choosing a language easier. The skin has its own specialization and directness. Specific information about this can be found on the Internet.
More to read:
If you do not have such a phenomenon, you will be surprised by two aspects: the demand for technology on the market and the complexity of development. I've been particularly interested in Java for a while now. The reason for this choice is simple: this language is very popular and in demand on the market. Besides, it’s not important to get married. Plus I want to be closer to web technologies.

To assess the popularity of Java and its leading position over the past three hours, you can, for example, look at the Popularity Index of our programming from the company TIOBE Software, which is engaged in continuous monitoring of search queries on the topic of programming.

Writing a preparation plan

My own plan is to begin my programmer’s path. Break down your training into stages and bring your skin to the next stage. To better understand how to program, and more precisely, what essentially happens when the processor compiles your first Hello, Word! You need advanced knowledge of computer architecture. If you have any clearings, you should put them away. Therefore, I recommend that you include PC architecture in your initial plan. Divide the processing of the selected language into stages to increase the complexity of the material. Clear information about the necessary knowledge can be obtained by studying nutrition before interview or assistance to applicants for positions in IT companies. How can you learn to program if you haven’t done it before? The answer is simple: to learn a foreign language, learn simple words from the beginning, then the rules that allow you to use them, then you will understand and understand them. To download Java, try to achieve the same algorithm.

Yak vivchiti Java?

Learn the syntax of the language right away: keywords, operators, rules for writing code. Go step by step to learn the complex structures of the language - methods, constructors, classes, libraries and frameworks. To understand how to program correctly, learn the algorithm and data structure of the program. This is very useful for forming a software design. This stage should be completed after learning the syntax of the movie.

And, no less, remember: your plan is not a static structure, as it cannot be modified every time. We noted this promising technology and development tool - feel free to include it in your plan!

How to learn to program in Java?

So, consider such basic sections as OOP, errors, richness, collections. All this is included in Java SE, the standard set of developer tools, and your plan is bound to start. After mastering Java SE, you can move on to Java EE, client-server programming technologies, databases, and web programming technologies. Here you will simply encounter a colossal amount of powerful frameworks and tools.

It’s not easy to learn everything right away, but the basics must be mastered at the time of practice. I would like to highlight the main ones: Git, Maven, Spring, ORM (Hibernate, JPA), REST, SQL, JUnit, Tomcat, JavaScript, JSP/JSTL, HTML/CSS, XML, knowledge of any database (MySql, PostgreSql). My plan looked something like this: Sichen

Methodology

To get started, you need to install the necessary tools for writing programs. If you want to understand how to learn to program Java, I would like to introduce such concepts as JRE, JDK, JVM. What is an IDE, what is a program, what is a compilation, what is a compilation of a program. To understand how to program Java, it is essential to understand the basic . Programming is a set of practical skills, as you expand the learning process. The more you practice, the more you will become healthier. Therefore, in addition to learning the theory, now add an hour of practice. The more the better. If you haven’t learned any practical skills yet, look at someone else’s code, repeat examples from books and articles on the Internet. A good way to learn how to program is to use a debugger to analyze other people's code. If you weren’t able to master the material right away, don’t hesitate, take another topic or repeat the lesson. You can return to important topics later: a look from a different perspective and a different source of information also helps to master new material.

Important important material can be summarized, or, more accurately, abstracted from the appendices. For this reason, I recommend using comments in the code to indicate key points. Good programming style, good code, and tips on how to program in Java can be found in The Java Tutorials section of the Oracle website. If it’s reasonable that the program hasn’t arrived, you can turn to your colleagues or people who have already walked this path. For whom it is not a good idea to know your own suitable strength for sprinkling. There you will be able to get a confirmation once again, as soon as you learn to program from scratch.

Select the information section

To learn how to program from scratch, check out everything you can get your hands on - online articles, videos, books, forums, official documentation.

Vikorista online courses

Since there is no way to work, online courses are one of the best options for getting started. It’s not a charming walk, but the stinks really help you join in with the training, especially if you’re starting to go through the basics. I am special, as can be seen from the plan. I was honored with the format of training, so I completed the entire course, including internship.

Let's do practice

Real practice, internship is an unknown part of learning in any process, and even more so in a program. This is the beginning of your path, and it will be a great plus for you to start. Vikorist if you can get closer to real robots. Try writing your own programs, download examples of ready-made programs on the Internet. It is possible to take part in cost-free initial internships with IT companies. Do not waste any opportunity to take part from a real project.

Summary

Starting programming is not an easy process. That's why you need to not get upset, but put yourself in check, keep yourself in good shape for the whole hour, and don't fail... to gain patience. Don’t worry about laying out the main directions and putting together a plan. Be assured: you will have to code and understand complex and insignificant information every day. Sometimes, they politely move on to another topic, and sometimes even more patiently hear the blessings. And your meta will be reached.

Programming is one of the most valuable skills for career growth, self-development and the creation of something amazing. Ten good things for those who are just starting their journey in the world of programming, from Lifehacker.

10. Explain why you want to program

Choosing directly from what you have started is important depending on what you want to learn to program and how long you are ready to devote to this process. If you want to become a programmer, the first thing you need to do is sign up for professional courses (Google has compiled a list of skills and courses for those who want to become software engineers). If you want to create games and websites for fun at any time, your best choice is interactive courses. Bloc having created an equal table of courses carefully for the purpose of the program.

9. Choose the right language

7. Try programs for children

Nina and the little ones are starting to program. Regardless of the fact that there are a lot of programs for children’s learning that are very simple, the activities from them (for example, Scratch) are suitable for any age. No matter how hard you are, kids can learn the basics of coding with animation programs (edX has a new course on Scratch).

6. Get faster with cost-free online trainings

Cost-free online trainings and projects (Codecademy, Hour of Code, etc.) can help you write your first programs. Basic guides from Khan Academy, Codecademy, Code.org and others will teach you the basics of programming and everything you need to create a game, website, or other project. It’s easy to find the right source for your programming, quickly. This is a good point, but you need to take this lesson on yourself.

5. Take an online course

Online courses from the program convey more extensive training in the same way as sites that demonstrate online training from the same language. Such courses are designed to teach basic skills over several months at the university level. I am a great student of the Harvard online course CS50 (you can take it without cost). There are also other possibilities. You can now gain exposure to the university level by taking one of 15 online courses.

4. Costless books with programming

If you are stuck on some problem, then you need to know the answer to your question, without forgetting about the witnesses. On GitHub you can find a large collection of over 500 free books on programming. A collection of e-books is also available, which supports 24 movie programs.

3. Whirl and roar

Another way to get started is to play games. At that time, as many programming assistants begin to program you to program simple or complex games, the initial sites with the games themselves: Code Combat and CodinGame - tools that you can spend an hour learning about.

2. Find a mentor or become one

There are a lot of programmers who are ready to help the next generation of programmers. Hack.pledge() is a site that will help you find a mentor. Or you can become a mentor for someone else. Learning from learning will help you remember information better.

1. Find someone else's code

It turns out that people who are not at all connected with IT will be drawn to the beauty of this sphere, which is intriguing, and set themselves the task of gradually mastering programming from scratch. And here you can often just get lost, not understanding where to start, and requiring a good foundation and a systematic approach.

I, recently in the same situation, googled, looked for manuals on Khabr (I found something: Ten joys for start-up programmers, Start-up program about startups and not only that...), but as a result, I was still afraid of going wild all for the joy of one good person , What is the plan for me? With the permission of this people, I am posting this plan on Habr - anyone else will need it. (Moreover, the list of books reaches the “golden fund” of literature in this sphere and is revised over time.)

UPD: The newcomers to the Raj will gain respect for the comments - this plan is actively and reasonedly adjusted there.

Stage I. Basics

Norton "Software and hardware organization of the IBM PC"
This book, regardless of how old it is, will remain there until it has become completely outdated. As a newbie, I can confirm that the story is completely clear and useful for a newbie in IT.

Guk "IBM PC hardware"
And this book should be read “over the top” - there will be information about how to cope in this sphere at the same time.

Stage II. Hardware

Krok 1

Morse, Albert "Architecture of the 80286 microprocessor"
Why take the 80286 microprocessor itself as a basis - it will become possible to proceed to the first stage.

Croc 2

Guk "PC Hardware Interfaces"

Guk "Interfaces of saving devices"

Stage III. Operating systems

Krok 1

Tanenbaum “Computer Architecture”

Croc 2

Kolisnichenko, Allen “Linux: outside the care”
From the original theory, we move on to the development of a specific operating system - from the Linux example.

Nemeth, Snyder, Hayne Kerivnitsa Linux Administrator

Stage IV. Vlasna programming

Krok 1

Kernighan, Richie “Mova Programming C”
Why was the language itself selected first for development? As the above-mentioned comrades told me, we will help to achieve the correct “programmer’s mind”, which would be difficult to achieve, starting from, say, Pascal. In addition, language C, as before, is being developed today and is suitable for both application and system programming.

Croc 2

Batig “The Mystery of Programming”:
Volume 1. Basic algorithms
Volume 2. Optimizing algorithms
Volume 3. Sorting and searching

Bentley "Perlini programming"

Do you want to master this practice? As they have already said on Khabri - “singingly, no more, no more, no fault of such a great number of bicycles.” These books will help you to become unique - and you will be able to write not just code, but good code.

Well, for starters, you can read a small series of lectures “Culture of programming” (author – O. Babii). This helps the start-up programmers to realize that their activities will not take place in a vacuum, but to inevitably enable interaction with other programs, from managers and back-office workers (and also include the need to dig then with their own authorities or in other people's programs).

Regularly eating newbie: what time will it take to eat everything? For the forecasts of my advisor, people who can spend their evenings and weekends on educational programming, reading and understanding the literature of the first three stages during training. At the fourth stage, there is also a lesson - reading can be accompanied by the practice of independently developing programs. The truth will come out - the hour will show.

I will be very grateful for your kindness and clarification.
