Description
In this assignment, you will modify your basic calculator to be a little more user-friendly. Make these modifications: 1. If the user enters an invalid menu option, allow them to try again until they enter a valid one. 2. If the user chooses three invalid menu options in a row, give them a message about trying again later and end the program. 3. After the user chooses a valid menu option and your program computes and displays the result, you should start over again by displaying the menu. This should continue until the user chooses a “Quit” menu option. Here are some example runs of the program: Menu 1. Add 2. Subtract 3. Multiply 4. Divide 5. Generate random number 6.
