How do you count the number of upper and lowercase letters in a string?

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,
3. Print all the counters.
