[Dev-C++] new comer to the world of Dev-C++

[hmbayati <hmb...@sb...>]

Hi everyone,
 
I am a new comer to the world of the Dev-C++ and C++ in general.  I am
trying to understand the GUI but I am not successful. I compiled and run
a very simple program like
 
#include <iostream.h>
 
void square()
{
cout << "hello, you are now in hadi's program.\n";
int num;
 
cout << "enter a number and I will give you its square.\n";
 
cin >> num;
 
cout << "the square of " <<num<<" is : "<<num * num << endl;
 
return;
}
 
I get a warning but when I run it I do not get any results.  Could
someone tell me what I am doing wrong?
 
I am on XP home edition and I set the project for  WIN 32 console.
 
Thanks for your help,
 
HB
