Question

In Lab 2, you created a menu for a simple calculator program. In this lab, you will add some functionality to the menu. Also, it is important to let the user know if they entered an invalid choice.

Write a program (or modify the one written for Lab 2) that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number (denominator) is 0.

1) Add two numbers

2) Subtract two numbers

3) Multiply two numbers

4) Divide two numbers

9) Exit program

The program should:

contain header comments as shown in class
display a "hello" message before presenting the menu
display the menu
prompt the user for selection
display the selection back to the user
if the selection was invalid, display error message to user and then go to goodbye message
if the selection was valid, prompt the user for two numbers
if the operation is division, and the second number is 0, display error message to user and then go to goodbye message
for any other scenario, perform the operation and display the results
display a "goodbye" message before exiting the program

HINT: The switch statement is ideal for menu-driven programs...

SAMPLE OUTPUT FOR VALID MENU SELECTION

You entered 2, subtract two numbers

SAMPLE OUTPUT FOR INVALID MENU SELECTION

You entered 5, an invalid selection

SAMPLE OUTPUT FOR ADDPlease enter two numbers, separated by a space: 2 3

2 + 3 = 5

SAMPLE OUTPUT FOR DIVISION ERRORPlease enter two numbers, separated by a space: 2 0

Division by zero is not possible
