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 :
- Scan string str from 0 to length-1.
- 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
- Print all the counters.
