declaring and using strings

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...)

PHP Code:

---

#include <iostream> 
#include <string>

using namespace std;

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


---

try that.

:)

:\Windows\Cpp1.cpp(3) : error C2871: 'std' : does not exist or is not a namespace
C:\Windows\Cpp1.cpp(6) : error C2065: 'string' : undeclared identifier

and thats what i get....

I removed the .h from the include header statements, and now it worked... man i hate this language... but thanks very much.. it works now...
