Why do my programs keep coming up as NTVDM CPU illegal instruction?

  1. Aug 19, 2013 #1
    I am using Windows XP Version 2002 and I am using freecommandLinetools as a compiler for the c++ language. Every time I write a program it always says it is an NTVDM CPU illegal instruction and it doesn't work, what's wrong with my programs? Here is an example:

    #include <iostream>

    using namespace std;

    int main()
    cout<<"HEY, you, I'm alive! Oh, and Hello World!\n";

    return 1;

    Is something wrong with my program? Or do I need a new compiler for my computer, or what ever? What's the problem? Thanks in advance!
