try to put this at the end:

1 2

int a;
cin>>a;

I use this in my console apps.
Or try to start your app from Command Promt

i put it before the return 0; and it did not work, did you mean for me to put it somewhere else?

<conio.h>

is a library that is only included in a Borland compiler. Try:

1 2 3 4 5 6 7 8 9 10

#include <iostream>
using namespace std;

int main ()
{
cout << "HELLO WORLD!! ";
cout << "Press ENTER to continue...\n";
cin.get();
return 0;
}

If you're on windows, you can use a nice little system("pause"); command.

Not really portable though.

the system("Pause") command displays that annoying "Press ENTER to continue..." thing. Try using cin.get(); right before the end of the code

1 2 3 4 5 6 7 8

#include <iostream>
using namespace std;

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

becomes

1 2 3 4 5 6 7 8 9

#include <iostream>
using namespace std;

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

@matanuragi
No one here is so stupid that you have to repeat yourself. <conio.h> is a non-portable library in any case.

@alexcook
There is a thread at the top of this forum entitled Console Closing Down. It deals specifically with your problem.

Good luck.
