Can anybody tell me why the following code will compile but when I try to run it the console opens and just closes immediately!!! It works when I comment out #include m.h .

#include <cstdlib>
#include <iostream>
#include "m.h"


int main(int argc, char *argv[])
{
    
    cout<<"HELLO"<<endl;
    system("PAUSE");
    return EXIT_SUCCESS;
}

#include<string>

I'm guessing that it executes and exits too quickly for you to see. Include the <stdio.h> library and make use of the getch() function (use it in place of your system("pause") call) - it waits for the user to press a key. This will hold the program/console window long enough for you to see your HELLO message.

Thanks mate. I'll give that a shot in the morning!

system("pause") should work fine at least on a windows machine.
The line 'return result' seems to be in no mans land in the header m.h this might be causing your problem.
Also cin.getch();can be used to pause and is part of the iostream header.
