swap_all

Language/Type: C arrays
Author: Allison Obourn (on 2020/09/14)

Write a function swap_all that accepts two arrays of integers and a length as parameters and swaps their entire contents.

int a1[3] = {12, 34, 56};
int a2[3] = {20, 50, 80};
swap_all(a1, a2, 3);

After the above code runs the arrays will have the following contents:

a1: {20, 50, 80}
a2: {12, 34, 56}

You may assume that the two arrays are the same length.

Function: Write a C function as described, not a complete program.
