The Program in C# Program to Print Result of Specified operations are given below:

using System;

namespace Calculator
{
    class Program
    {
        static void Main(string[] args)
        {
             Console.WriteLine("Hello Codeauri Famuly, Enter the first number and Second number here to find their arithemtic operations: ");
            Console.WriteLine("Well, enter the first number: ");
            int num1 = Convert.ToInt32(Console.ReadLine());
            
            Console.WriteLine("Well,enter the second number: ");
            int num2 = Convert.ToInt32(Console.ReadLine());
            
            Console.WriteLine("Now, enter the operation (+, -, *, /): ");
            string operation = Console.ReadLine();
            
            int result = 0;
            switch (operation)
            {
                case "+":
                    result = num1 + num2;
                    break;
                case "-":
                    result = num1 - num2;
                    break;
                case "*":
                    result = num1 * num2;
                    break;
                case "/":
                    result = num1 / num2;
                    break;
                default:
                    Console.WriteLine("Invalid operator");
                    break;
            }
            if (result != 0)
            {
                Console.WriteLine("Okay, the result of " + num1 + " " + operation + " " + num2 + " is: " + result);
            }
        }
    }
}

Output:

Hello Codeauri Famuly, Enter the first number and Second number here to find their arithemtic operations:
Well, enter the first number:
90
Well,enter the second number:
20

Now, enter the operation (+, -, *, /):

Okay, the result of 90 – 20 is: 70

Pro-Tips💡

Here are the steps by steps execution of above program:

1. First, the program uses the using System directive to include the System namespace, which provides access to the Console class for reading and writing to the console.
2. Next, the program declares a namespace called Calculator. All the classes in the code will be part of this namespace.
3. The Program class is declared inside the Calculator namespace. This class contains the Main method, which is the entry point of the program.
4. The Main method starts by printing a message to the console asking the user to enter two numbers and an arithmetic operator.
5. Then, the program prompts the user to enter the first number, which is read from the console and stored in the num1 variable.
6. Similarly, the second number is read from the console and stored in the num2 variable.
7. The user is then prompted to enter an arithmetic operator, which is stored in the operation variable.
8. A switch statement is used to perform the corresponding operation based on the value of operation. If the operation is +, the sum of num1 and num2 is stored in result. If the operation is -, the difference of num1 and num2 is stored in result. If the operation is *, the product of num1 and num2 is stored in result. If the operation is /, the division of num1 by num2 is stored in result. If the value of operation is not one of the four supported arithmetic operators, the program prints a message to the console indicating that the operator is invalid.
9. Finally, if the value of result is not 0, the program prints the result of the operation to the console.
