Simple c++ question
Author
I'm having a problem using cin. The code used to work perfectly but know it doesn't.
string name;
cout << "Please enter name: ";
cin >> name;
When compiling I get
error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
This error started when I tried to overload the << operator to use one of my own classes with cout but I didn't touch this piece of code and have now commented this out in case it would cause any problems but it still doesn't work.
I am including iostream and have using namespace std;

You didn't introduce your own variable called "cin" by any chance?
The following works. Check your includes.
#include <string>#include <iostream>#include <istream>#include <ostream>int main(){ std::string name; std::cout << "Please enter name: "; std::cin >> name;}
You need to:
#include <string>
Since string is part of the std namespace, you must use:
using namespace std;
or
std::string
#include <string>
Since string is part of the std namespace, you must use:
using namespace std;
or
std::string

Thanks everyone, but it's working again now, I didn't have string.h included only iostream.h.
I didn't think that I needed to include both as the string type was recognised.
Thanks again.
