Reverse the Order of Three Letters in C#

This C# program prompts the user to enter three letters, one by one. Once the user has provided all three characters, the program will display them in reverse order.

The program demonstrates the use of basic string handling, console input/output operations, and simple variable assignments. This is an excellent example for beginners to practice working with characters, user input, and output formatting.

The execution of the program follows these steps:
1. Ask the user for three letters (characters).
2. Store each letter in a separate variable.
3. Display the entered letters in reverse order.

This exercise helps reinforce the concept of input handling, variable assignments, and output formatting in C#.

Objective

Write a C# program to ask the user for three letters and display them in reverse order.

Example C# Exercise

 Copy C# Code 
using System;

class Program
{
    static void Main()
    {
        // Ask the user for three letters
        Console.Write("Enter the first letter: ");
        char letter1 = Console.ReadKey().KeyChar;
        Console.WriteLine(); // Move to the next line

        Console.Write("Enter the second letter: ");
        char letter2 = Console.ReadKey().KeyChar;
        Console.WriteLine(); // Move to the next line

        Console.Write("Enter the third letter: ");
        char letter3 = Console.ReadKey().KeyChar;
        Console.WriteLine(); // Move to the next line

        // Display the letters in reverse order
        Console.WriteLine("\nReversed order: " + letter3 + letter2 + letter1);
    }
}

 Output

//Example 1:
Enter the first letter: A
Enter the second letter: B
Enter the third letter: C

Reversed order: CBA

//Example 2:
Enter the first letter: x
Enter the second letter: y
Enter the third letter: z

Reversed order: zyx
