C++, removing #include or #include in class header

Question

I want to remove, if possible, the includes of both and from my class header file. Both string and vector are return types of functions declare

Answer 1

With a very few exceptions, you are not allowed to add things to the std:; namespace. For classes like vector and string, you therefore have no option but to #include the relevant Standard header files.

Also, notice that string is not a class, but a typedef for basic_string.
