Today, many are interested in whether it is possible to learn to program from scratch.
We have all heard stories that people who are engaged in this business have huge incomes, they travel to Bali every weekend and in the first months of their work they were able to buy apartments for all their relatives.
Basically, this is not far from the truth, but experience and reputation are required for such results. And you need to start with the simplest. We will consider what steps a person who does not know anything about writing programs need to follow in order to travel to Bali and buy real estate in the future.

Step one. Preparation
Often, novice programmers cannot achieve success for the simple reason that they were initially unable to correctly prioritize.
They present this craft as something romantic, dynamic - just some kind of constant action.
In films, this process is shown quite differently from what it really is.
Moreover, there is generally the actual writing of codes is not displayed, we are only shown the events that revolve around it.
The films also show that any person without knowledge, experience and even without gray matter in the brain can become a programmer. In this case, you can recall the film "Frames".
So if you just imbued with the spirit of all kinds of films and want to start "coding" on your own, programming is clearly not for you.
Here's the truth about the craft in question - programming is:
- hours, and sometimes days of monotonous work, during which you cannot relax, you must always be focused;
- endless learning in pursuit of the latest trends in this area;
- similar projects with customers who themselves do not know what they want and how it should look like.
As for the latter, then you must it is worth watching a video about seven red lines of different colors, one of which is in the form of a kitten. In principle, this is close to the truth, since customers often demand the impossible. It also happens that they order something, but they are constantly not satisfied with the result.

If you understand all this and are ready to plunge into the wonderful world of programming, then proceed to the next step.
Step two. First language selection
There are a huge number of programming languages. According to some estimates, their number has already reached several thousand.
In general, C is one of the most simple languages which provides the foundation for everything else. Moreover, its elements are used in many other systems and programs.
But it is interesting that in good educational institutions, as well as in the courses, students learn languages in the following order:
1 Pascal.
2 C ++.
3 PHP and everything related to web programming as well SQL(this is a system designed to work with databases through queries).
- Web(website development, online systems and everything related to this) - html(although it cannot be called a full-fledged programming language), PHP, Perl, Python, Ruby, Java, Groovy, as well as ASP.NET technology.
- Custom software(all kinds of programs like reference books, browsers, instant messengers, etc.) - Delphi, C, C ++, C #.
- Custom software for mobile devices - Java, Objective-C.
- Machine development(work with microprocessors and other devices, design of robotics) - Assembler, modifications by C.
Someone can also add so-called 1C programming to this list. Do not trust profane and ignorant people! This is not programming at all.
When you become familiar with the basics of the work in question, you will understand why it can be said that way.
Choose what you like best.
Advice: Make your choice right away! You must know exactly in which direction you will develop and what to study in the future.
Most professionals also advise to start your learning with Pascal. This option will allow
You write the simplest programs and have general idea about the craft in question as a whole.
We can say that Pascal is a kind of bridge. A person who just knows mathematics well can move through it into the world of programming.
Attention! Whatever company you find yourself in after training, you will be retrained for yourself. Therefore, you should simply understand the very principle of writing programs. And for this there is nothing better than Pascal.
Step three. Exploring Compilers
For reference: Compiler- This is a technical solution designed to translate the entered commands into machine instructions, roughly speaking, into zeros and ones, that is, into an interpretation on which the machine will understand what to do.
Actually, you will write all your programs and execute them in compilers.
If you decide to follow our advice and start with Pascal, then you should download Free Pascal. This compiler is absolutely free and is distributed on the official website.
As you can see, it looks quite "old-fashioned", but programming begins with this. By the way, the C ++ compiler looks pretty much the same.
It's called Turbo C ++ (you can download it).
As far as Pascal is concerned, there is also GNU Pascal, Turbo / Borland Pascal, TMT Pascal, and Virtual Pascal. And for C ++ you can use Borland C ++, +, Dev C ++, GCC and Eclipse.
But this, as we said above, is only the beginning. You can't stop there. When you have made a choice regarding your direction, you can move on to more complex compilers.
Here is a list of the most popular compilers today. depending on the areas of activity:
ConcerningDelphi, then the compiler is called there. There is also Embarcadero Delphi and some other modifications. Delphi 7 can be downloaded from many sites, for example. If you chose C, C ++, or C #, then you need Microsoft Visual Studio. You can download it directly on the official website of the manufacturer.
Talking aboutAssembler and other languages that are practiced in robotics, then here you need to download MASM right away if you work on Windows. In general, depending on your chosen field of activity and the company for which you get a job, compilers can be very different. Some firms write their own code processing solutions. Therefore, if you have chosen robotics, it is better to study the relevant books and do everything as they say. We will talk about this later.
There are also many online compilers. They are useful in that they serve many programming languages and do not require installation - very convenient!
The most popular ones are:
This is a unique service that allows you to create several virtual computers and do whatever you want on them, including compiling ciphers.
The virtual machines will be running. On them you can at least delete system folder, install absolutely any program, and so on.
Now let's get down to writing your first cipher (code). This can be done even without books and lengthy instructions.
Step four. First code
For the first code, we will use the first language and the first compiler, which we advised to choose above. This is Pascal and Free Pascal.
One of the most simple programs is written as follows:
1 Download Free Pascal from the link above and run it on your computer.
2 Enter the following: "program [name];"... That is, if you want the program to be called "hello", you must enter "program hello;".
3 Enter the "begin" statement... This means that the code that later needs to be executed has started.
4 We use one of the most common constructions in Pascal "Writeln (‘ [some text] ’);"... It just displays the text on the screen. Which is contained in parentheses and quotes. We will introduce the combination "Hello, world!"... This is how they usually start their journey into the big world of software development. So the next line will look like "Writeln (‘ Hello, world! ’"); ".
5 To complete the executable cipher, enter "end."(always with a dot at the end).
6 Now press the button "F9" to run what you wrote. You will see the words appear on the screen "Hello, world!"... This was required!
To get started with other languages, books usually also provide instructions for writing "Hello, world!" , that is, an instruction that just prints such simple text to the screen.
So, you've mastered your first cipher! A start. Now move on to intensive training.
Step five. Take online training
Advantage online lessons in the fact that you see everything clearly, and from beginning to end.
Therefore, it is better for beginners to start their journey with online trainings. Here best courses in Russian:
If you've chosen Python, check out McGrath's Programming Python for Beginners.
Step seven. Stay up to date
When you have sufficiently studied the material in the chosen direction and already have some experience, you need to constantly monitor the trends in the development of the software market.
Here's what we're talking about:
All this is needed so that you can rebuild in time.
Let's say you decided to do a certain type of programming, learned the technology and are ready to go to work to apply for a resume.
Your data is reviewed, but they say that the company needs a specialist in a different profile.
So that you have as few such situations as possible, you should always know what areas of development are currently the most popular.
Important! Study both global trends and the situation in your city where you are going to work. If you want to be a freelancer, study orders on various exchanges and forums.
All this will allow you to develop and work in the right direction, without wasting precious time.
This is very important in our time, since programming trends change, not so much in a few months, in a few days!
If you learned some method of writing programs two or three years ago, now all this is definitely irrelevant.
Step eight. Find a teacher
It is best to find a personal mentor who will tell you what and how best to do in a particular case.
This option has many positive sides, the main of which is the presence of a personal approach to you personally.
Also, if problems arise, the teacher will help you solve them. A You can find a mentor in the following ways:
1 Apply to university... Yes, training programs in post-Soviet countries can be quite outdated, but the basics, the very principle of programming, you will definitely be able to comprehend a certain basis of everything
2 Various courses. There are a huge number of courses where people gather in some kind of office and the teacher, just like in a university, explains this or that concept. Usually these courses are very intensive, and students quickly master the necessary information.
Of course, the services of a teacher will cost money, but the study will be very productive, and you can learn a lot. the information you need.
Step nine. Analyze someone else's work
This is very interesting method which allows you to develop very quickly. The fact is that it is very difficult to understand someone else's code, even a few professional programmers are capable of this.
If you do this at the very beginning of your activity, for sure, you will be able to reap great results in the future.
Moreover, it will allow you to become a project manager in the future, since you will have the ability to adjust the work of other people.
More specifically, you need to do the following:
- think about how you could optimize the cipher, that is, reduce the listing;
- look for errors and flaws without and with a compiler;
Work and, accordingly, earnings in your pocket! If this is not the case, train further. Have you at least learned what tasks you need to complete in order to be hired.
In any case, give it enough time and then you will succeed!
