Question

Write a C program that does the following!

Count all words in the file. A word is any sequence of characters delimited by white space or the end of a sentence, whether or not it is an actual English word. 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 "ea" in "real" counts as one syllable, but the "ea" in "regal" count as two syllables). However, an "e" at the end of a word does not count as a syllable. Each word has at least one syllable even if the previous rules give a count of zero. Count all sentences. A sentence is a group of words terminated by a period, colon, semicolon, question mark, or exclamation mark. Multiples of each of these characters should be treated as the end of a single sentence. For example, "Fred says so!!!" is one sentence. The index is computed by: index = 206.835 - 84.6 * (#syllables/#words) - 1.015 * (#words/#sentences) rounded to the nearest integer. Input Your program will read the text to be analyzed from a file. The filename is to be given as a command line parameter to the program. You will name the program fleschIndex.c and will execute the code on a file by doing the following: ./fleschlndex

This is a vanilla test file. There is nothing tricky or abnormal about the
contents of this file. The counts output by student programs should be
exact as everything here is unambiguously covered by the spec.
