Question

Problem 1: Consider 2 integer arrays, x and y, of the same size (assume size = 10). Initialize array x with random numbers between 1 and 100. Write code that fills array y with values such that each element of y is the corresponding value of x multiplied by its index.

#include <iostream>

        for (int i = 0; i < size; i++)

                /*THIS STATEMENT IS USED TO DISPLAY NEW VALUES IN Y*/

        }
