Several operations

 Objetive

Write a C# program to print on screen the result of adding, subtracting, multiplying and dividing two numbers typed by the user. The remainder of the division must be displayed, too.

It might look like this:
Enter a number: 12
Enter another number: 3
12 + 3 = 15
12 - 3 = 9
12 x 3 = 36
12 / 3 = 4 <
12 mod 3 = 0

 Example Code

using System; // Importing the System namespace to use Console functionalities

// Main class of the program
class Program
{
    // Main method where the program execution begins
    static void Main()
    {
        // Declaring two variables to store the numbers entered by the user
        int num1, num2;

        // Asking the user to enter the first number and reading the input
        Console.Write("Enter a number: ");
        num1 = Convert.ToInt32(Console.ReadLine());

        // Asking the user to enter the second number and reading the input
        Console.Write("Enter another number: ");
        num2 = Convert.ToInt32(Console.ReadLine());

        // Calculating the sum of the two numbers
        int sum = num1 + num2;
        // Printing the result of the addition to the screen
        Console.WriteLine("{0} + {1} = {2}", num1, num2, sum);

        // Calculating the difference between the two numbers
        int difference = num1 - num2;
        // Printing the result of the subtraction to the screen
        Console.WriteLine("{0} - {1} = {2}", num1, num2, difference);

        // Calculating the product of the two numbers
        int product = num1 * num2;
        // Printing the result of the multiplication to the screen
        Console.WriteLine("{0} x {1} = {2}", num1, num2, product);

        // Calculating the quotient of the division
        int quotient = num1 / num2;
        // Printing the result of the division to the screen
        Console.WriteLine("{0} / {1} = {2}", num1, num2, quotient);

        // Calculating the remainder of the division
        int remainder = num1 % num2;
        // Printing the remainder of the division to the screen
        Console.WriteLine("{0} mod {1} = {2}", num1, num2, remainder);
    }
}
