How do I include the string header?

Question

I'm trying to learn about strings, but different sources tell my to include different headers.

Some say to use <string.h>, but others mention "apstring.h". I was able to do some basic stuff with apstring, but I've been told the other one is more powerful. When I include <string.h> and try to declare some string variables, however, I get errors. What is the proper usage?

Answer 1

You want to include <string> and use std::string:

#include <string>
#include <iostream>

int main()
{
    std::string s = "a string";
    std::cout << s << std::endl;
}

But what you really need to do is get an introductory level book. You aren't going to learn properly any other way, certainly not scrapping for information online.
