I like others have been experimenting with C++ code and have discovered
why some people can build C++ programs and others cannot.

using the program:

#include<iostream.h>

int main(int argc, char **argv)
{
  cout << "Hello World\n";
  return 0;
}

Compiled with g++ the program dumps core when executed with an illegal
system call.

When compiled with c++ the program works correctly.
