What to learn after having basic concepts of C++, other than C++?

Answer 1

my opinion is to learn C++ deeply now, after you know the basics it will be good if you learn the other thing and have a complete view of it, recommend you to do this:
There are many options available to you after learning C++, let me mention some:

1- Master C++: It’s fairly known that one month is not enough to master a language like C++, because you need to dive deeper into some essential topics like Algorithms and Data Structures. I recommend reading books. (You may want to view Stack Overflow’s The Definitive C++ Book Guide and List)
2-Learn a C++ Library: If you are passionate about game development, then why don’t you try something like the OpenGL library?
3-Practice Competitive Programming: It will help you write more efficient codes more quickly. There are hundreds of thousands of sources online. Try Codeforces and start submitting solutions!
4-Contribute to Open Source: It is definitely the best choice for those who are seeking a job. It’s like doing an internship with world’s best alive programmers! So go ahead and sign up for a GitHub account and start pulling requests!
