Multiply Three Numbers

Write a C# Sharp program to print the output of the multiplication of three numbers entered by the user.

C# Sharp multiplication (*) operator :

The multiplication operator (*), which computes the product of its operands. Also, the dereference operator, which allows reading and writing to a pointer.

Note:

All numeric types have predefined multiplication operators.
The * operator is also used to declare pointer types and to dereference pointers.
User-defined types can overload the binary * operator. When a binary operator is overloaded, the corresponding assignment operator, if any, is also implicitly overloaded.

C# sharp Exercises: Multiplication of three numbers

Sample Solution:

C# Sharp Code:

using System;

// This is the beginning of the Exercise6 class
public class Exercise6
{
    // This is the main method where the program execution starts
    public static void Main()
    {
        // Declaration of variables to store three numbers
        int num1, num2, num3;

        // Prompting the user to input the first number to multiply
        Console.Write("Input the first number to multiply: ");
        // Reading the first number entered by the user and converting it to an integer
        num1 = Convert.ToInt32(Console.ReadLine());

        // Prompting the user to input the second number to multiply
        Console.Write("Input the second number to multiply: ");
        // Reading the second number entered by the user and converting it to an integer
        num2 = Convert.ToInt32(Console.ReadLine());

        // Prompting the user to input the third number to multiply
        Console.Write("Input the third number to multiply: ");
        // Reading the third number entered by the user and converting it to an integer
        num3 = Convert.ToInt32(Console.ReadLine());

        // Calculating the result of multiplying the three numbers
        int result = num1 * num2 * num3;

        // Displaying the multiplication formula and the result to the console
        Console.WriteLine("Output: {0} x {1} x {2} = {3}",
                            num1, num2, num3, result);
    }
}

Sample Output:

Input the first number to multiply: 2                                                                         
Input the second number to multiply: 8                                                                        
Input the third number to multiply: 5                                                                         
Output: 2 x 8 x 5 = 80
