// EXAMPLE
#include <string>
int iIntAsInt = 658;
std::string sIntAsString = to_string(iIntAsInt);

/* SYNTAX
to_string(<your-integer>)
*/

// ----------------------------------- BEFORE C++ 11
// EXAMPLE
#include <sstream>

int iYourInt = 5;
std::stringstream ssYourInt_AsStream << iYourInt;
std::string sYourInt_AsString = ssYourInt_AsStream.str();
