I would assume that your teacher expects that you have the resources (textbook, handouts, class lectures) to be able to do this on your own. You should try to do the assignment and if you have trouble then post your code and explain where you are having the problem.
People are willing to help when you show some effort.
Call your factorial function from within a loop in the main () function.
The loop should increment the input from 0 until the maximum integer for which
we can compute/store its factorial. Print the numbers and their factorials, i.e., your
columns will be n and n!.
