The Program in C# Sharp which is a Menu-Driven Program to perform a simple calculation inputted by user is given below:

using System;

namespace MenuDrivenCalculator
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                Console.WriteLine("Hello Codeauri Family,enter number below to perform the simple arithemtic calculation: ");
                Console.WriteLine("1. Addition");
                Console.WriteLine("2. Subtraction");
                Console.WriteLine("3. Multiplication");
                Console.WriteLine("4. Division");
                Console.WriteLine("5. Exit");
                Console.WriteLine("Enter your choice (1-5):");

                int choice = int.Parse(Console.ReadLine());
                if (choice == 5)
                    break;

                Console.WriteLine("Enter two numbers:");
                double num1 = double.Parse(Console.ReadLine());
                double num2 = double.Parse(Console.ReadLine());

                switch (choice)
                {
                    case 1:
                        Console.WriteLine("Result: " + (num1 + num2));
                        break;
                    case 2:
                        Console.WriteLine("Result: " + (num1 - num2));
                        break;
                    case 3:
                        Console.WriteLine("Result: " + (num1 * num2));
                        break;
                    case 4:
                        Console.WriteLine("Result: " + (num1 / num2));
                        break;
                    default:
                        Console.WriteLine("Invalid choice");
                        break;
                }
                Console.WriteLine("\n");
            }
        }
    }
}

Output:

Hello Codeauri Family,enter number below to perform the simple arithemtic calculation:

1. Addition
2. Subtraction
3. Multiplication
4. Division
5. Exit
   Enter your choice (1-5):
   1
   Enter two numbers:
   9099
   1099
   Result: 10198
   Hello Codeauri Family,enter number below to perform the simple arithemtic calculation:
6. Addition
7. Subtraction

    Enter your choice (1-5):

Pro-Tips💡

Here are the step by step execution of above program:

1. The first line using System; is a directive that imports the System namespace in the program.
2. The namespace keyword defines a container for a set of related classes and is used to organize code into logical units. In this case, the namespace is named MenuDrivenCalculator.
3. The class keyword defines a class. In this case, the class is named Program.
4. The Main method is the entry point of the program. It is called when the program starts.
5. Inside the Main method, there is a while loop that continues to run until the user enters the value 5. This loop presents the menu of options to the user and allows them to repeatedly perform calculations.
6. The Console.WriteLine method writes a line of text to the console. In this code, it is used to display the menu of options, the result of the calculation, and other messages to the user.
7. The int.Parse method converts a string representation of a number to an integer. It is used to parse the user’s choice of operation.
8. The if statement checks if the value of choice is equal to 5. If it is, the break statement is executed and the program exits the loop.
9. The double.Parse method converts a string representation of a number to a double-precision floating-point number. It is used to parse the two numbers entered by the user.
10. The switch statement is used to perform the calculation based on the user’s choice of operation. It has a case for each operation and a default case for invalid inputs.
11. The Console.WriteLine("\n"); statement writes a blank line to the console, which is used to separate the outputs of each iteration of the loop.
