Write the definition of the readandcount function the


Please enhance this program.

Write the definition of the readAndCount function. The function should read the input line, character by character, counting the number of words (a sequence of letters) and the number of occurrences of each letter.

The array to hold the number of occurrences of each letter is the parameter letterCount. Store the number of occurences of 'a' at index 0, 'b' at index 1, and so forth. Be sure to account for both upper and lowercase letters. Note that the index can be computed easily from the character using subtraction of ASCII codes (which are just the 'values' of characters in C++).

To count words you need a way of determining when you have completed reading a sequence of letters. There are a few different ways to do this.

Be sure your method of counting words counts the last one.
