Q:This information is taken from http://en.wikipedia.org/wiki/Automated_Readability_Index. The Automated Readability Index (ARI) is a computed value that estimates the understandability of text. You are to write a program that inputs text and calculates the ARI using the formula below:
ARI = 4.71(total_characters / words) + 0.5(words/sentences) ÃÂ 21.43
In calculating the number of characters, donÃÂt count punctuation. For this assignment, you may assume that
ÃÂ All sentences end with . ? or !
ÃÂ Other punctuation characters will be limited to , ; :
Your program should prompt the user for the name of a file containing text to be processed. After processing, display
ÃÂ number of characters (not including spaces and punctuation)
ÃÂ number of words
ÃÂ number of sentences
ÃÂ ARI score
Sample input (from page 404 of the CPS 150 textbook with extra punctuation) and associated output.
Abstraction occurs in programming as well. In order to focus on the
bigger picture of creating a working application, a programmer needs
to be able to use certain objects and routines without having to be
concerned about the details of their implementation! You have been
doing this since the beginning of this text when you used objects
such as cin, and cout and functions such as pow and sqrt? All you
need to know: to use the objects, or functions; is what they do and
the interface, for using them.
