Getting Started with C# Programming
Objective
The objective of this exercise is to write a C# program that multiplies three user-entered numbers and prints the result using formatted output with {0}. You will also include a comment with your first and last name on the first line of the code.
Use of {0} and comments. Write a C# program to ask the user for three numbers and display their multiplication. The first line should be a comment with your first and last name. It should look like this:
Example C# Exercise
Show C# Code
// First and Last Name: John Doe
using System;
namespace MultiplyThreeNumbers
{
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, number3, result;
// Ask the user to enter the first number
Console.Write("Enter the first number to multiply: ");
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 to multiply: ");
number2 = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double
// Ask the user to enter the third number
Console.Write("Enter the third number to multiply: ");
number3 = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double
// Perform the multiplication
result = number1 * number2 * number3;
// Display the result using formatted output with {0}
Console.WriteLine("The result of multiplying {0}, {1}, and {2} is: {3}", number1, number2, number3, 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 to multiply: 12
Enter the second number to multiply: 23
Enter the third number to multiply: 2
The result of multiplying 12, 23, and 2 is: 552
