 As others told, you should use <iostream>, or (at least in Dev-C++5)
you'll have a warning for antiquated header. So:

#include <iostream>
using namespace std;

 Should it be int main ()?

if you don't see any result, it could be that you need to wait for an
input, adding a final cin.get () before returning, as others suggested in
another post, because you compiled a program for console, and when you
make it run in a window it close it immediately on returning. Or you can
execute your program really in a console (starting cmd.exe).
