Divide if not zero - C# Programming Exercise

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

class Program
{
    // Main method where the program execution begins
    static void Main()
    {
        double firstNumber;  // Declaring a variable to store the first number entered by the user
        double secondNumber; // Declaring a variable to store the second number entered by the user

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

        // Asking the user to enter the second number and reading the input
        Console.Write("Enter the second number: ");
        secondNumber = Convert.ToDouble(Console.ReadLine()); // Converting the input to a double

        // Checking if the second number is not zero
        if (secondNumber != 0) // If the second number is not zero
        {
            // Performing the division and displaying the result
            Console.WriteLine("The result of division is: {0}", firstNumber / secondNumber); // Printing the division result
        }
        else // If the second number is zero
        {
            // Displaying an error message when division by zero is attempted
            Console.WriteLine("I cannot divide"); // Printing the error message
        }
    }
}

 Output

Case 1:
Enter the first number: 10
Enter the second number: 2
The result of division is: 5

Case 2:
Enter the first number: 7
Enter the second number: 0
I cannot divide

Case 3:
Enter the first number: -12.5
Enter the second number: 2.5
The result of division is: -5
