Can someone break this down for me so I can understand what a factorial does?
I'm working with C and what I read doesn't make sense to me.

(factorial) returns the number of ways that n number of objects can be arranged. For example there are 7 possibilities that can go in the first place, then 6 that can go in the second spot, and so forth. Hope this helped happy coding.
