Hello I just started a class on programming. The firs program was to 
write "Hello World". I downloaded the compiler "Magic C." When I ran 
the compiler it said "variable cout not found". Here is the code I 
typed. This is the way it was shown in the example in the book.

#include <io.h>


int main ()
{
  cout << "Hello World!";
  return 0;
}

I assume I missed something.
