I have just started on C++. Today I tried to compile the following source
and I got some error messages.

#include <iostream>
#include <string>

using namespace std; //introduces namespace std

union myunion2
{
 struct Point3d
 {
  float x;
  float y;
  float z;
 }
 pt;

 struct Rectangle
 {
  int l;
  int t;
  int r;
  int b;
 }
 rect;
};

void main( )
{
 myunion2 mu;

 mu.Point3d::x = 1.0f; //this line gives the error. Illegal use of
non-static member
 //rest of the code
 cout << "This is a test" ;
 ;
}

I got the code from a book called "Using C++" by Rob McGregor, published
1998. I tried to compile the source using both C++ Builder and Metrowerks
CodeWorrier with no luck. Any help on the proper usage of nested structure
and scope resolution operator will be appreciated.
