String and character functions in c++

Question

why sololearn has not included string and character functions in its c++ course ?

Answer 1

You haven't finished the C++ course.

I recall them mentioning strings but not covering it in depth. If you check cppreference.com and cplusplus.com you can find full in-depth info for C++ STL including C++20's standard.

Remember SL just gets you started, it takes time to learn a language.
