Character Type Checker in C#

This C# program prompts the user to input a single character and checks whether it is an alphabet letter, a digit, or a special character. The program uses character classification methods to identify the type of character and outputs the result, demonstrating conditional logic and built-in C# functions for handling character data.

Source Code 💻 #

using System;

class Program
{
    static void Main()
    {
        // Prompt user to enter a character
        Console.Write("Enter a character: ");
        char inputChar = Console.ReadKey().KeyChar;
        Console.WriteLine(); // For new line after input

        // Check if the character is an alphabet, digit, or special character
        if (Char.IsLetter(inputChar))
        {
            Console.WriteLine($"{inputChar} is an alphabet.");
        }
        else if (Char.IsDigit(inputChar))
        {
            Console.WriteLine($"{inputChar} is a digit.");
        }
        else
        {
            Console.WriteLine($"{inputChar} is a special character.");
        }
    }
}

Explanation #

• The program prompts the user to input a character.
• It uses the Char.IsLetter() method to check if the character is an alphabet letter (a-z or A-Z).
• The Char.IsDigit() method is used to check if the character is a digit (0-9).
• If the character is neither a letter nor a digit, it is classified as a special character.
• The result is printed accordingly.

Example #

• Input: a

• Output: a is an alphabet.

• Input: 5

• Output: 5 is a digit.

• Input: @

• Output: @ is a special character.
