The function must return true if the sum of B1 greater than the sum of B2, otherwise it must return false Suppose you have a file called "MyData.txt". In this file, a list of unknown number of users ages are listed. Write a C++ program to read the ages and save the following in a file called "OutData.txt: 1. Total number of users ages 2. The average value of all ages 3. Total number of children, where a user with age less than or equal to 13 is considered as a child.
