Must be coded using C:

4. (20 pts) Write a function that computes two sums from the elements of an array of integers. Each element of the array contributes to one of the two sums, depending on whether the element itself is even or odd. Turn in your code and input/result together. Your function definition should look like: void sum (int a, int n, int *even elt sum ptr, int *odd elt sum ptr)
