Write a program that mimics a calculator. The program should take as input two integers and the operation to be performed (addition, subtraction, multiplication, and division). It should then output the numbers, the operator, and the result. (For division, if the denominator is zero, output and appropriate message). The program will only stop when user select Exit, your program should also include function and looping structure.
