find_pairs

Language/Type: C arrays double
Author: Cynthia Lee (on 2018/02/03)

Write a function named find_pairs that accepts an array of real numbers (as double[]), its size (as int), and a second array of real numbers (as double[]) and its size (as int). It returns the number of pairs (a, b) that can be made where a is a number from the first array, b is a number from the second array, and a < b. For example, if double arr1[] = {1.0, 2.0, 3.0}; and double arr2[] = {3.0, 2.0, 2.0, 0.0, 3.0};, then the call of find_pairs(arr1, 3, arr2, 5) returns 6. You may assume that each size given as input accurately represent the size of its array.

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