Multiplying Two User-Entered Numbers in C#

In this exercise, you will create a simple C# program that takes two numbers as input from the user, multiplies them, and then displays the result. This exercise will help you practice working with user input, performing multiplication, and displaying the output. It is a great way to become familiar with basic arithmetic operations in C# and to understand how to handle user input and output in a console application.

Objective

The objective of this exercise is to write a program that accepts two numbers entered by the user, multiplies them, and prints the result.

Write a C# program to print the result of multiplying two numbers which will be entered by the user.

Example C# Exercise

 Copy C# Code 
// This program multiplies two numbers entered by the user and displays the result
using System;

namespace MultiplyTwoNumbers
{
    class Program
    {
        // The Main method is where the program execution begins
        static void Main(string[] args)
        {
            // Declare variables to store the numbers
            double number1, number2, result;

            // Ask the user to enter the first number
            Console.Write("Enter the first number: ");
            number1 = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double

            // Ask the user to enter the second number
            Console.Write("Enter the second number: ");
            number2 = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double

            // Perform the multiplication
            result = number1 * number2;

            // Display the result
            Console.WriteLine("The result of multiplying {0} and {1} is: {2}", number1, number2, result);

            // Wait for the user to press a key before closing the console window
            Console.ReadKey(); // This keeps the console window open until a key is pressed
        }
    }
}

 Output

Enter the first number: 8
Enter the second number: 7
The result of multiplying 8 and 7 is: 56
