strings in structs

I have a problem with strings in structs that I'm having a hard time finding a solution for, so I searched for a C++ forum and ended up here. I hope that you guys can provide me with a solution, I'm learning at the moment so my knowledge with C++ is limited.

Let me get straight to the problem;
When I have a string in a structure and try to print it with cout I get a bunch of errors.
Here's an example:

Code:

---

#include <iostream>


int main()
{
        struct familyMember
        {
                int nAge;
                string strName;
        };

        familyMember sMemberOne;
        sMemberOne.nAge = 21;
        sMemberOne.strName = "Charles";

        cout << "The first member is named " << sMemberOne.strName; //This is the line that the compiler complains about.
        return 0;
}

If anyone is interested, this is the output I get from my compiler:

Thanks in advance.

#include <string>

Code:

---

#include <iostream>
#include <string>
using namespace std;

int main()
{
  // rest of code...
}

I feel very stupid right now, how could I forget that?
Thanks for the fast replies, I can move on with my project now.
