Count Uppercase, Lowercase, special character and numeric values

Given a string, write a program to count the occurrence of Lowercase characters, Uppercase characters, Special characters, and Numeric values.

Examples:

Input : #GeeKs01fOr@gEEks07
Output : 
Upper case letters : 5
Lower case letters : 8
Numbers : 4
Special Characters : 2

Input : *GeEkS4GeEkS*
Output :
Upper case letters : 6
Lower case letters : 4
Numbers : 1
Special Characters : 2

Approach :

  1. Scan string str from 0 to length-1.
  2. check one character at a time on the basis of ASCII values
    • if(str[i] >= 65 and str[i] <=90), then it is uppercase letter,
    • if(str[i] >= 97 and str[i] <=122), then it is lowercase letter,
    • if(str[i] >= 48 and str[i] <=57), then it is number,
    • else it is a special character
  3. Print all the counters.
