Write a C program to check whether a character is an alphabet, digit or special character.

#include <stdio.h> void main() {      char ch;           printf("Input a character: ");      scanf('%c', &ch);           /* Checks whether it is an alphabet */       if(ch>='a' && ch<='z') || (ch>='A' && ch<='Z')       {       printf("This is an alphabet.\n");       }             //      whether number is number or not       else if(ch>='0' && ch<='9')       {       printf("This is a digit.\n");       }             //   character is special       else       {       printf("This is a special character.\n");       }   }

Simple Output :

Enter a character : @

this is a special character
