Programming language is c++

Question 1 Write a program that reads integers until the user enters a 0, and then displays the total sum of the integers. Use a function to do this (you cannot make a "new main" function, with the entire program on it). Avoid using just a void function with no parameters, that will not help you to understand the usefulness of functions. Please provide 4 test cases at least. Corresponding output The total is 20 Example Input Enter a value or 0 to quit : 3 Enter a value or 0 to quit : 2 Enter a value or 0 to quit : 15 Enter a value or 0 to quit : 0 Enter a value or O to quit : 1 Enter a value or 0 to quit : -2 Enter a value or O to quit : 4 Enter a value or O to quit : 0 The total is 3
