Check input character is alphabet, digit or special character
All characters whether alphabet, digit or special character have ASCII value. Input character from the user will determine if it’s Alphabet, Number or Special character.
ASCII value ranges-
- For capital alphabets 65 – 90
- For small alphabets 97 – 122
- For digits 48 – 57
All other cases are Special Characters.
Examples :
Input : 8 Output : Digit Input : E Output : Alphabet
C++
// CPP program to find type of input character #include <iostream> using namespace std; void charCheck(char input_char) { // CHECKING FOR ALPHABET if ((input_char >= 65 && input_char <= 90) || (input_char >= 97 && input_char <= 122)) cout << " Alphabet "; // CHECKING FOR DIGITS else if (input_char >= 48 && input_char <= 57) cout << " Digit "; // OTHERWISE SPECIAL CHARACTER else cout << " Special Character "; } // Driver Code int main() { char input_char = '$'; charCheck(input_char); return 0; } |
Java
// Java program to find type of input character import java.io.*; class GFG { static void charCheck(char input_char) { // CHECKING FOR ALPHABET if ((input_char >= 65 && input_char <= 90) || (input_char >= 97 && input_char <= 122)) System.out.println(" Alphabet "); // CHECKING FOR DIGITS else if (input_char >= 48 && input_char <= 57) System.out.println(" Digit "); // OTHERWISE SPECIAL CHARACTER else System.out.println(" Special Character "); } // Driver Code public static void main(String[] args) { char input_char = '$'; charCheck(input_char); } } // This code is contributed by vt_m. |
Python3

C#
// C# program to find type of // input character using System; class GFG { // Function to check type // of input character static void charCheck(char input_char) { // Checking for Alphabet if ((input_char >= 65 && input_char <= 90) || (input_char >= 97 && input_char <= 122)) Console.WriteLine(" Alphabet "); // Checking for Digits else if (input_char >= 48 && input_char <= 57) Console.WriteLine(" Digit "); // Otherwise Special Character else Console.WriteLine("Special Character"); } // Driver Code public static void Main() { char input_char = '$'; charCheck(input_char); } } // This code is contributed by vt_m. |
PHP
<?php // PHP program to find type // of input character function charCheck($input_char) { // CHECKING FOR ALPHABET if (($input_char >= 65 && $input_char <= 90) || ($input_char >= 97 && $input_char <= 122)) echo " Alphabet "; // CHECKING FOR DIGITS else if ($input_char >= 48 && $input_char <= 57) echo " Digit "; // OTHERWISE SPECIAL CHARACTER else echo " Special Character "; } // Driver Code $input_char = '$'; charCheck($input_char); // This code is contributed by Sam007 ?> |
Output :
Special Character
