Write a C++ program that prompts the user to enter 15 integers and stores them in an array. The program then determines and outputs which numbers in the array are sum of two other array elements. If an array element is the sum of two other array elements, then for this array element, the program should output all such pairs. Hint: You have to use 3 (for) loops (i, j, and k) to go through all the elements in the array. Then you have to check if the item at index i (i starts from 0) equals the sum of the items at index j (j starts from 0) and k (k starts from j + 1), then print out the index of these two items. Sample of run: Input: 10 17 23 65 34 6 18 27 35 110 75 25 100 24 19 Output: list [0] = 10 is the sum of: list [1] 17 is the sum of: list [2] 23 is the sum of: list [1], list [5]; list [3] = 65 is the sum of: list [4] 34 is the sum of: list [0], list [13]; Activate Wi Go to Settings t
