Count the number of occurrences of each character in the string and print the characters and their counts in alphabetical order (first uppercase and then lowercase) if they occur at least once in the string. Return the number of unique characters in the string (capital and lowercase are considered different). Function specifications Name: charCount() Parameters (Your function should accept these parameters IN THIS ORDER): input_text string: The text string containing characters between A to Z and a to z Return Value: int: The number of unique letters in the input string The function should print the number of occurrences for every letter that appears at least once in the input string, beginning with capital letters.

3. Word Counter Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is "Four score and seven years ago" the function should return the number 6. Demonstrate the function in a program that asks the user to input a string then passes it to the fune- tion. The number of words in the string should be displayed on the screen. Optional Exercise: Write an overloaded version of this function that accepts a string clás object as its argument.
