About computer c programming

Write a recursive and a non recursive function that returns the factorial of n (n!). Use both functions in a program that reads the value n and prints the result n!.
For a nonnegative integer n, the factorial of n is defined by
0!=1, n!=n*(n-1)*… 3*2*1 for n>0 or equivalently,
0!=1, n!=n*((n-1)!) for n>0 (recursive form)
