Getting Started with C# Programming
Objective
The objective of this exercise is to develop a C# program that prompts the user to enter four numbers, calculates their average, and displays the result in a clear and formatted way.
Write a C# program to calculate and display the average of four numbers entered by the user.
Example C# Exercise
Show C# Code
// First and Last Name: John Doe
using System;
namespace AverageCalculator
{
class Program
{
// The Main method is where the program execution begins
static void Main(string[] args)
{
// Declare variables to store the four numbers
double num1, num2, num3, num4, average;
// Prompt the user to enter the first number
Console.Write("Enter the first number: ");
num1 = Convert.ToDouble(Console.ReadLine()); // Read and convert the input to a double
// Prompt the user to enter the second number
Console.Write("Enter the second number: ");
num2 = Convert.ToDouble(Console.ReadLine());
// Prompt the user to enter the third number
Console.Write("Enter the third number: ");
num3 = Convert.ToDouble(Console.ReadLine());
// Prompt the user to enter the fourth number
Console.Write("Enter the fourth number: ");
num4 = Convert.ToDouble(Console.ReadLine());
// Calculate the average
average = (num1 + num2 + num3 + num4) / 4;
// Display the result
Console.WriteLine("\nThe average of {0}, {1}, {2}, and {3} is: {4}", num1, num2, num3, num4, average);
// 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: 10
Enter the second number: 20
Enter the third number: 30
Enter the fourth number: 40
The average of 10, 20, 30, and 40 is: 25
