2. Write a function called even product. It takes a single integer parameter, call it n. It takes the absolute value of n and returns the product of the even numbers from 2 up to that absolute value. 3. Write a function called sum product. It takes 5 int parameters. Call them nl, n2, n3, sum and product. It computes the sum and product of the first three parameters and returns them as call by reference parameters in sum and product. sum_product does not return a value
