Hello friends!

We will reveal to you one secret that you will not have to learn even in universities. You have probably seen many who, after 5 years of studying at a university for a programmer, did not understand what OOP is (Object Oriented Programming).

Usually the scientific definition of OOP is:

OOP = polymorphism + encapsulation + inheritance

or so

Object-Oriented Programming (OOP) is a programming methodology based on the representation of a program as a collection of objects, each of which is an instance of a particular class, and the classes form an inheritance hierarchy

But what this means is really incomprehensible. And we will tell you in simple human language.

Now let's forget about programming and think about yourself. About your human body. Each of us has different parts of the body and different organs. The question is - can we completely control ourselves? The question is not idle - and if you think - then you will understand the answer - NO. For example, you want to raise your hand - it's easy. You want to hold your breath for a while - it's easy. You want to say something - it's easy. And now you want to stop your heart with the power of thought - can you? No, you can not. Or, for example, you want to stop digesting food in the intestines with the power of thought - can you? Not. Or you want not to feel pain - you cannot either.

Why are we so strangely arranged? Why can we do something with ourselves - but something not? The fact is that we ourselves have a protection against the fact that we do not break ourselves and die because of inaccuracy. There are fences inside of us that we cannot overcome. The truth is, there are such people - they are called yogis - who still know how to overcome these fences for a while: they walk on hot coals and it does not hurt them, they can hold their breath for 15-20 minutes, slowing down all processes in their body so much that they do not die.

So the greatest secret is that the OOP is the science of building artificial fences inside your own program. Fences from yourself. You yourself forbid a lot of things to do inside your own program - so as not to accidentally break it. And the science of fences is 99% of programming. And 1% is actually self programming without fences.

The science of fences, in addition to the methods of building fences, also includes the science of superpowers for overcoming them in special cases (yes, these are the same yogis walking on coals).

OOP is necessary for writing large projects, especially those that exceed 100,000 lines of code. But for smaller programs, the OOP often creates excessive difficulties and makes these projects difficult at all.

For example, the first version of the Linux kernel was written by its creator, Linus Torvalds, without OOP in pure C language, and it was just 100,000 lines of code.

But later, the entire core was rewritten by the developer community in the object-oriented C ++ language. And now the Linux kernel exceeds 18,000,000 lines of code.

As we said in one of our articles:

Programming itself is just 20 words - and everyone can learn it very quickly. And in the first years of training you will learn to express any of your ideas with these 20 words. But when you conceive your IT company, when you plan to program a grandiose team project - OOP will save you from many mistakes.

Now you know what OOP is and most importantly - why it is needed. Come and learn programming with us - it's fun!
