Thread: explanation please

My understanding appears to be wrong; in the following snippet I define a Print as a routine but when I call it from within Main nothing happens; am I completely on the wrong track here about sub routines? I appreciate it is a silly bit of code but I am trying to understand calling a defined routine from another.

Code:

#include <windows.h>
#include <iostream>
#include "ShortColours.h"

using namespace std;

int Print()
{cout<<"dddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd"<<'\n';
    for(int x(1);x<20;x++)
    cout<<"John"<<'\n';
    return 0;
 }

int main ()
{
   Print;
   return 0;
}
