# Check Special Character ## Write a program to check special character Check if given character is a special character (not a letter or a number). ```txt Input : @ Output : Special Character ``` --- ```c #include void charCheck(char ch){ if ( !(((ch >= 65 && ch <= 90) || (ch >= 97 && ch <= 122))) && !(ch >= 48 && ch <= 57) ) printf("Special Character"); else printf("Not a Special Character"); } // Driver Code int main() { char ch; scanf("%c", &ch); charCheck(ch); return 0; } ``` ```cpp #include using namespace std; void charCheck(char input_char){ if ( !(((input_char >= 65 && input_char <= 90) || (input_char >= 97 && input_char <= 122))) && !(input_char >= 48 && input_char <= 57) ) cout << "Special Character "; else cout<<"Not A Special Character"; } // Driver Code int main() { char input; cin>>input; charCheck(input); return 0; } ``` ```csharp using System; using System.Text.RegularExpressions; class SpecialCharacters{ public static void onlySpecialchars(String str) { String regex = "[^a-zA-Z0-9]+"; Regex rgex = new Regex(regex); if (str == null) { Console.WriteLine("Not a Special Character"); return; } MatchCollection matchedAuthors = rgex.Matches(str); if (matchedAuthors.Count != 0) Console.WriteLine("Special Character"); else Console.WriteLine("Not a Special Character"); } public static void Main(String []args) { String str = "@"; onlySpecialchars(str); } } ``` ```java import java.util.*; public class SpecialChar { public static void main(String[] args) { String specialCharacters = " !#$%&'()*+,-./:;<=>?@[]^_`{|}"; System.out.println("Enter the Character : "); Scanner scanner = new Scanner(System.in); char c = scanner.next().charAt(0); if (specialCharacters.contains(Character.toString(c))) { System.out.println("Special character"); } else { System.out.println("Not a Special character"); } } } ``` ```javascript // function to check for special character function checkSpecialCharacter(char) { const reg = /[^a-zA-Z0-9]/g; return reg.test(char); } const callFun = checkSpecialCharacter("*"); console.log(callFun); ``` ```kotlin package com.includehelp.basic import java.util.* fun main(args: Array) { val scanner = Scanner(System.`in`) //Input Character print("Enter Character : ") val char = scanner.next()[0] when { char.isDigit() -> char.isLetter() -> else -> println("Special Character") } } ``` ```swift import Swift import Foundation let characterset = CharacterSet(charactersIn: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789" ) let givenCharacter = "@" if givenCharacter.rangeOfCharacter(from: characterset.inverted) != nil { print("Special Character") } else { print("Not a Special Character") } ``` ```typescript function checkSpecialCharacter(str: string) { let isSpecialCharacter = "false"; const format = /[`!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/; if (format.test(str)) { isSpecialCharacter = "true"; } else { isSpecialCharacter = "false"; } console.log(isSpecialCharacter); } checkSpecialCharacter(">"); ``` ```scala object HelloWorld { def main(args: Array[String]): Unit = { val string = scala.io.StdIn.readLine(); if(string.matches("^[a-zA-Z0-9]*$")){ println("String does not contain Special Charaters"); } else { println("String contains Special Charaters"); } } } ``` ```dart void main() { final regExp = RegExp( r'[\^$*.\[\]{}()?\-"!@#%&/\,><:;_~`+=' "'" ']' ); final string = '@'; if(string.contains(regExp)) print("Special Character"); else print("Not a Special Character"); } ``` ```php <>,|=_+¬-]/', $string)) { echo "one or more 'special characters' found"; } else { echo "no 'special characters' found"; } ?> ``` ```perl print "Please enter a character: "; my $char = ; chomp $char; if ($char =~ /[^a-zA-Z0-9]/) { print "Special Character\n"; } else { print "Not a Special Character\n"; } ``` ```python import re # function to check for special character def run(string): regex = re.compile("[@_!#$%^&*()<>?/\|}{~:]") if regex.search(string) == None: print("Not a special character found!") else: print("This is a special character") # driver code if __name__ == "__main__": user = input("Input:") run(user) ```
