i am a programmer who has just compiled a program in C++ but whenever i try to run the exe file it wont run because main() returns 0, and somewhere in my configuration settings is a setting that makes programs close when they return the value. Does anyone know how to turn off this setting or create a batch file to turn it off when my program runs?

What tells you it wont run? Is there an error?

Because a lot of programs will return 0 as a standard, it's there to signify to the OS that the program ran successfully... There's not a setting you can change to kill any program that returns 0... So what is it that tells you it wont run?

i worked it out on another program from the internet-in the program tab under properties a box that had 'close on exit' written on it was checked.when i unchecked it stopped just executing for a second when i clicked on it to staying there. but when i looked under properties for the same checkbox in my program, it didnt have it?

Can you post your code? i think you may be falling into the common pitfall of not keeping your program running after it's done what you want it to...

i wont post the one im working on, its a private database, but heres a famous one that does the same thing on my computer:

#include <iostream>

int main()
{
std::cout "Hello World!\n"
return 0
}

Bobna

and yes that sounds about right

Yep, fix:
Alternatively run your program from a command prompt in order to see what it did after it finishes.

sorry but i dont know how to use cin.get()?

Bobna

maybe i could establish a loop that doesnt break until 'quit' is entered?

Bobna

hmmm....

Bobna

wait no i fixed it with this code:

int userchoice;
int closer = 5;
std::cout << "enter 5 to continue";
std::cin >> userchoice;

while (1)
if (userchoice == closer)
break;
else
continue;
