What libraries and frameworks are worth learning in c++?

Question

IT education

What is worth learning in c++ after learning the basics of ,winsock and qt, a bit of ue4? What are the frameworks and libraries that are most commonly used in real projects and worth learning? It is desirable that there be also the name of the framework / library and the area with which it is associated) It’s just that the language is seriously large and used in many places, but it’s difficult to understand what to learn, because it’s not popular on freelance (because the web rules there, and this is no longer a plus) .)

Answer 1

It is useless to learn libraries - it's like learning a telephone directory - there seems to be a lot of knowledge, and they are useful, but you can only benefit from them when someone needs Ivanov's phone number.
Really salable skills are the ability to deal with a library you are unfamiliar with, the ability not to faint at the sight of a kiloton of linking errors, understanding the difference between static and dynamic linking, and so on.
That is, you need to develop the ability to solve problems in C ++ and search for information on the Internet.
They will ask you to draw a textured spinning cube - you can literally type this wording into Google, from there you will get information that cubes can be drawn manually by writing all the 3d code yourself (this is interesting and exciting, by the way), or there are three whales opengl, d3d and vulkan that draw
At this stage, you can take any of the trio, look for initial lessons and try to use the library.
In short, it is not the knowledge of the telephone directory by heart that is useful in the market, but the ability to search for phones in it.
