C Program  To Calculate Value Of npr

In the following program, we are calculating the value of nPr based on the given values of n and r. nPr can also be represented as P(n,r). The formula of P(n, r) is n! / (n – r)!. For example P(6, 2) = 6! / (6-2)! => 720 / 24 = 30. We have implemented the same logic in the below C program. Let’s See the example of C Program To Calculate The Value Of npr.
