PROGRAMMING PROJECTS

΢΢΢ Project 6.1. Flesch Readability Index. The following index [ 7 ] was
invented by Flesch as a tool to gauge the legibility of a document
without linguistic analysis.

ȗ Count all words in the file. A word is any sequence of characters

delimited by white space, whether or not it is an actual English
word.

ȗ Count all syllables in each word. To make this simple, use the

following rules: Each group of adjacent vowels (a, e, i, o, u, y)
counts as one syllable (for example, the Ȓeaȓ in Ȓrealȓ contributes
one syllable, but the Ȓe ș aȓ in Ȓregalȓ count as two syllables).
However, an Ȓeȓ at the end of a word doesn't count as a syllable.
Also, each word has at least one syllable, even if the previous rules
give a count of 0.

ȗ Count all sentences. A sentence is ended by a period, colon,

semicolon, question mark, or exclamation mark.

ȗ The index is computed by

Index = 206.835

ɨ 84.6 ¶ ( Number of syllables / Number of words )

ɨ 1.015 ¶ ( Number of words / Number of sentences )
