The program below is executing fine but when I enter the last of 10

numbers and the final output(shows the average of the 10 numbers) is displayed,

I get the following error message:

Run-Time Check Failure #2 - Stack around the variable 'numbers' was

corrupted.

If someone could explain what this error message is for, I would appreciate it.

Thanks
