Review: CountLetters The CountLetters application is limited to counting letters in a single word. Modify the CountLetters
application to count the letters in an entire phrase, which contains spaces. Care must be taken to ignore the
spaces and any other nonalphabetic character found in the phrase. Be sure to change comments and vari-
