using c programming

1. The of a nonnegative integer n is written nr (pronounced -n factorial") and is defined as follows: n! n x (n -1) x (n-2) x x 1 (for values of n greater than or equal to 1) and n 1 (for n 0). For example, 5 5 x 4 x 3 x 2 x 1, which is 120. Write a program that reads a nonnegative integer and l) computes and prints its factorial if the number input is smaller than 3 2) computes and prints the square ofthe factorial value for the input number if the input number is larger or equal to 3. For example, ifyou input 6, the output should be 720 720 51,840. 3) Show the result for both cases
