Program to count vowels, consonant, digits and special characters in string.

08 Mar, 2022
Given a string and the task is to count vowels, consonant, digits and special character in string. Special character also contains the white space.Examples:  
Input : str = "geeks for geeks121"
Output : Vowels: 5
         Consonant: 8
         Digit: 3
         Special Character: 2

Input : str = " A1 B@ d  adc"
Output : Vowels: 2
         Consonant: 4
         Digit: 1
         Special Character: 6
