Value returning function

[bbunn77]

So I was wondering how would you go about returning a value from one function and using it another. Say i have function - int x( int z)(just a random code) and this function just has the user input a value. How can i have the returned value used in my second function, which would just manipulate the value by adding or subtracting?

You just pass it to the second function like anything else.
