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

Question

Please don't confuse with the title as it was already asked by someone but for a different context

The below code in Visual C++ Compiler (VS2008) does not get compiled, instead it throws this exception:

std::ifstream input (fileName);   

while (input) {
  string s;
  input >> s;
  std::cout << s << std::endl;
};

But this code compiles fine in cygwin g++. Any thoughts?

Answer 1

Have you included all of the following headers?

• <fstream>
• <istream>
• <iostream>
• <string>

My guess is you forgot <string>.

On a side note: That should be std::cout and std::endl.
