Character Arrays, getline, cin.get...

Hi
I need the code for a function that
- retrieves a string of characters from the user (ex: Hello world!)
- outputs the number of each character, upper or lowercase in this exact format: (using an array)

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
0 0 0 0 1 0 0 1 0 0 0 2 0 0 1 0 0 1 0 0 0 0 1 0 1 1

- this is the function declaration (which is called in function main that declares char inString[MAX]....MAX = 81 (global variable))
void DisplayNumLetters (char inString[])

Thank you
