I need this in C programming.

5. Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are x, x2. x is x = (x1 +X2 + X3 + X4 + X5)/5 and the standard deviation is: , x4, and xs, then the mean Your program must contain at least the following functions: a function that calculates and returns the mean and a function that calculates the standard deviation
