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
