Or, copy these file(s) to your CSE account using the following command:

1511 fetch-activity array_sum_prod

Your task is to add code to this function in array_sum_prod.c: 

// Calculates the sum and product of the array nums.
// Actually modifies the  variables that *sum and *product are pointing to
void array_sum_prod(int length, int nums[length], int *sum, int *product) {
    // TODO: Complete this function
}

The above file array_sum_prod.c contains a function array_sum_prod, which should find the sum and the product of the values stored in the array. It should write these values into the integers referenced by the pointers in the input to the function.

Unfortunately, the provided function doesn't actually work. For this lab exercise, your task is to complete this function.

The file also contains a main function which you can use to help test your array_sum_prod function. It has two simple test cases.

This main function will not be marked -- you must write all of your code in the array_sum_prod function.

You may modify the main function if you wish (e.g. to add further tests), but only the array_sum_prod function will be marked.

Examples

dcc -o array_sum_prod array_sum_prod.c 
./array_sum_prod 
Sum: 20, Product: 360
Sum: 10, Product: 24
