$(6)$ Objective

In this lab, you will write a C$++$ program that implements a simple calculator using a switch statement.

The program will prompt the user to choose an operation from the menu by entering a number. The

available operations are addition, subtraction, multiplication, division, and exiting the program. The

program will repeat until the user enters $0$ to exit.

Follow the instructions below to complete the lab:

Step $1$: Program Structure

Begin by creating a new $C++$ source file and include the necessary headers $($iostream$).$

Define the main$()$ function to start the program execution.

Step $2$: Display the Menu

Inside the main$()$ function, display the menu options to the user:

$1$ Calculator Menu:

Addition

Subtraction

Multiplication

Division

$.$ Exit

Step $3$: Input the User's Choice

Prompt the user to enter a number corresponding to their chosen operation.

Read the input and store it in a variable $($e$.$g$.,$ choice$).$

Step $4$: Implement the Switch Statement

Use a switch statement to perform the appropriate arithmetic operation based on the user's choice

For each case, prompt the user to input the required numbers for the selected calculation.

Perform the arithmetic operation and display the result to the user.

Step $5$: Handle Invalid Choices

Implement a default case in the switch statement to handle invalid choices.

Display a message to inform the user that their choice is invalid.

Step $6$: Repeat the Program

After completing a calculation, repeat the process from Step $2($display the menu and get the user's

choice$)$ until the user enters $0$ to exit the program.

Step $7$: Test Your Program

Compile and run your program.

Test it with different inputs to ensure it works correctly, including testing the error handling for invalid

choices.

Step $8$: Use Meaningful Variable Names and Comments

Use descriptive variable names to make the code clear and easy to read.

Add comments to explain the purpose of each section of the code.
