I'm taking a intro class in a c++ class and i have been skiping class because honestly it's the type of stuff that if you see some one do it you pretty much got it down... but i'm stuck since i haven't been in class in a whiel and we have a major preogram to built and i can't remember how to end a program if an invalid input is entered help?

So you skip class because the stuff is so easy that you seen it once and you have it down. Yet you don't know it, because you haven't been to class in awhile? You could probably use a while loop

I guess that pretty much blows a hole in this theory.

If you just want to kill the program, maybe assert is what you're looking for.

Look at the example for assert in the link I posted. You have to form some logical expression that will evaluate to true if the input is valid and false otherwise. If false, assert fails and the program terminates.
