a set-up question

[jian peng]

Hi, there,

I am using gcc 3.2.2 shipped with Redhat 9. I tried to
compile the following simple C++ program:

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

int main()
{
  cout << "Please enter your first name: ";
  string firstName;
  cin >> firstName;

  cout << "\nWelcome to the world of C++, "
<<firstName << "\n";

}

The compiler apparently did not like this program and
complained a lot:

Any suggestion? Thank you for the help!
