Is learning a standard C ++ library a good idea?

Question

I am a beginner C ++ programmer, and I am still learning the basics, but I have a simple question about the standard library and STL in C ++, I think this is not from The Core language, I mean this library just to simplify programming and portability, and this means that if I learn and master the rules in C ++, I can create my own, I mean, in general, this calling experience by practicing. Example: cout is a standard output function, but if I want to program GUI software for Windows, for example, I will never just look at it !! My question is: is this true? And if not, then why?

Answer 1

Actually, you cannot say that he is a C ++ programmer without a good knowledge of the standard library. And writing your own is a very bad idea. I highly recommend that you get a copy of Nikolai Josuttis ’s book and accept the strength that it will give you. You will learn, for example, that threads are not only good for doing I / O in console applications.

And maybe you should also take a look at the Good idea / bad idea, should I redefine most of C ++? , which discusses the pros and cons of writing your own standard library.

You will not use everything from STL, but MAN are the classes of strings and containers, and sometimes the algorithms are useful!
