I drivin myself up the wall here... I'm using vc++... and all i am tryin to do is declare and use a string variable....

#include <iostream>
#include <string>

void main()
{
string firstBinaryDigit;
string secondBinaryDigit = "h";
cout << "Enter first binary number";
cin >> firstBinaryDigit;
cout << "\nEnter second binary number";
cin >> secondBinaryDigit;
}

but i get this error... it won't recognize string...
:\Windows\Cpp1.cpp(6) : error C2065: 'string' : undeclared identifier


whats up ?

I realize there is Cstring class, but I haven't been able to get that to recognize either.... (plus I need to use the std String class since its intended to run on a unix system...)
