Question

Working with sentinels

Write a C++ program that will prompt the user to read in a list of numbers. Use a sentinel value to end the input list. calculate the average of the numbers. Display how many numbers were read in, each number read in and the average to the user. Write the results to a file. Be sure to add a check for division by 0. For example, if the user enters the sentinel as the first number, the program will terminate. That means that the counter will be 0 and the total will be 0 because no data will be processed.

Answer 1

The question requires a C++ program to read numbers using a sentinel, calculate their average, handle division by zero, and write outputs to a file.

Step-by-step explanation:

The question asks for a C++ program that uses a sentinel value to end the input of numbers and calculates the average of these numbers. The program should also display the count of numbers, each number entered, and the average. It must include a check for division by 0 and write the results to a file. This task will help develop skills in control structures, file I/O, and error handling in C++ programming.

This C++ program prompts the user to enter a list of numbers, calculates the average of the numbers, displays the numbers and average to the user, and writes the results to a file.

In this C++ program, we will prompt the user to enter a list of numbers and use a sentinel value to end the input list. We will calculate the average of the numbers, display how many numbers were read in, each number read in, and the average to the user. Additionally, we will write the results to a file. To handle division by zero, we will add a check to ensure the denominator is not zero.
