Write a program, that takes an integer number from user and adds (sums) all the digits of that numb For example, if user enters 123 , the program should be able to provide a result of 6(1+2+ Similarly, if user enters 546 , the program should be able to provide a result of 15(5+4+6). U loops to solve this exercise. Below is the expected output: Write a C++ program that asks user to enter a number on each iteration of the loop. If user enters 1, the loop should break else should continue asking for numbers from user. At the break of the loop, the program should display the sum of all the numbers entered by the user except 1. Below is the expected output
