Question

•Write a C++ program (practice4.2.1.CheckNumbers.cpp) that lets the user enter a series of integers, one at a time using a loop.

•The program will check and display if the input number is even or odd, and then calculate the sum of all input numbers. If the input number is zero (0), print out the sum of all inputted numbers, and then end the entire program.

Analyze the problem:

•Part-1: should use a for loop, while loop, or do-while loop to solve the problem?

ANS: Since starting point of the program will always be to ask user to enter an integer number, and then check that number. So use a do-while loop in the program is more appropriate for user inputs.

•Part-2 (bonus-part): use a while loop inside the do-while loop to do input validation.

•Part-3: If user entered zero (0), exit the do-while loop, but not exit the entire program, still need to print out the sum. So use break;statement
