C++ Question. I need a miracle from the C++ gods...... - Tilted Forum Project Discussion Community

so I have my C++ program, everything works fine. It even gives me output.

the last lines of my code in main() are

char x;
cin>>x;

its just to keep the window open until i press a key to allow the program to close.

but when i enter a character and press enter, it crashes.. or rather. windows says it crashes...

when i delete the cin, it just crashes on termination,

WHY??!!!!

thanks....... just about going crazy with this...

It would help to see more code... It doesnt sound like an error with those last lines.

You should ask this in Computers.

What it sounds like - though without looking at most/all of the code:

You've got a memory leak somewhere in your code - allocating dynamic memory (either through malloc or new) and not deleting it. Then, when you get to the end of the program, it doesn't properly know how to delete/free it, and crashes.

Also, if you are using namespace std in this program, you can use the following command to get a "keypress" pause...

system("pause");

Again, this only works if you are doing this at the top:
using namespace std;

Did you remember to

return 0;

?

Well, with my limited knowledge of C... here's a basic program that will close when you press a key.

Code:

#include <stdio.h>
int a;
main()
{
     scanf( %d, a );
     return 0;
}

Mind you, my C is a tad rusty, but that should do it.
