This is my first attempt at any code. I've got a C++ tutorial with lots of sample code to refer to. It tells you to compile some of the code to test your compiler. I installed a default installation of xcode 2.0. When I have a .cpp file open in xcode it won't allow me to compile. Everything under Build is greyed out as is all but three under Debug. Any suggestions on how I should do this?
Here's the code I used:

Code:
                                // Chapter 1 - Program 1 - CONCOM.CPP

#include <iostream.h>       /* This is the stream definition file */

void print_it(const int data_value);

int main()
{
const int START = 3;        // The value of START cannot be changed
const int STOP = 9;         // The value of STOP cannot be changed
volatile int CENTER = 6;    /* The value of CENTER may be changed
                                 by something external to this
                                 program.                          */
int index;                  /* A normal C variable                 */

   for (index = START ; index < STOP ; index++)
      print_it(index);

   return 0;
}     /* End of program */


void print_it(const int data_value)
{
   cout << "The value of the index is  " << data_value << "\n";
}




// Result of execution
//
// The value of the index is  3
// The value of the index is  4
// The value of the index is  5
// The value of the index is  6
// The value of the index is  7
// The value of the index is  8

Xcode can only build projects, not individual files. You can make a project with just that file in it, or you can use the C++ command line tool (c++ myfile.cpp).

Make a new C++ tool project and replace the contents of the main.cpp file with what you posted and it should compile.

Thanks, it worked.
