Question

ONLY USE VISUAL STUDIO (NO JAVA CODING)

VISUAL STUDIO -> C# -> CONSOLE APPLICATION

1. In this part of the assignment, you are required to create a C# Console Application project. The project name should be A3<FirstName><LastName>P2. For example, a student with first name John and Last name Smith would name the project A1JohnSmithP2.

Write a C# (console) program to calculate the number of shipping labels that can be printed on a sheet of paper.

This program will use a menu that includes the following options:

1. Enter/Update paper size
2. Enter/Update label size
3. Generate report
4. Exit

The first menu option will ask the user to enter the width and height of the paper.

The second menu option will ask the user for the width and height of the label.

The third menu option will calculate the number of whole labels that can fit on the sheet and the report the following:

1. Paper Size
2. Label Size
3. Number of Labels
4. Total Paper Area (Square inches)
5. Area used by labels (Square Inches)
6. Amount of unused paper (Percentage of Total Paper Area)

Your program must:

1. Have at least 3 methods other than the main method
2. Handle any potential errors using try/catch statements. The error message output should display at least 3 different types of error (or status) messages, depending on what the user has done incorrectly. Your program should be able to catch all possible errors, it should not crash.
3. Verify that the user has entered valid data for the paper and label dimensions before the report can be generated.

Print a welcome message including a program description and your name before the menu is displayed
