error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

Question

Here's my code, how do I fix this error?

#include "stdafx.h" #include <iostream>  using namespace std;  int main() {     string title = "THE WORLD OF PIRATES";     cout << title << endl;     cout << " Welcome to the world of pirates";      cin.get();      return 0; } 

The error is

binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion) 

Answer 1

You forgot to #include <string>

using std::string without including it's header works on some compilers that indirectly import parts of <string> into their <iostream> or other headers but that's not standard and shouldn't be relied upon. Also they often break when you try to output a string since they only included a part of the implementation and are missing the part that implements the operator<<.
