Question: Give one example of a function which calculates n!, the product of all positive integers from 1 to n. n! = 1 * 2 *

Give one example of a function which calculates n!, the product of all positive integers from 1 to n.

n! = 1 * 2 * ..( n-1) * n

Use C++ to calculate it. Have a Recursive and an iterative version. Test both versions for n = 2, n=3, and n=4. Submit the .txt file for the tests and the .cpp file.
