Code:
#include <iostream.h>
#include <string>
using namespace std;

int main(){

	string string1 = "hello";

	cout << string1 << '\n';

return 0;
}
I get the error:

error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (or there is no acceptabl
e conversion)

why?
