TREE PROJECT C$++$

There is a real program developed by a computer company that reads a report $($ running text $)$ and issues

warnings on style and partially correct bad style. You are to write a simplified version of this program with the

following features:

Statistics: A statistical summary with the following information:

$,$ Total number of words in the report

Number of unique words

Number of unique words of more than three letters

Average word length

Average sentence length

An index $($alphabetical listing$)$ of all the unique words $($see next page for a specific format$)$

Style Warnings: Issue a warning in the following cases:

Word used too often: list each unique word of more than three letters if its usage is more than $5\%$ of the

total number of words of more than three letters

$,$ Sentence length : write a warning message if the average sentence length is greater than $10$

Word length : write a warning message if the average word length is greater than $5$

Input: From the keyboard: The name of the file containing the text to be analyzed

From the file: The report to be analyzed.

Output

Write the following information to a file:

The name of the input file

The statistical summary of the report $($ see Statistics above $)$

The style warnings $($ see Style Warnings above $)$

Data Structures

A BST of unique words in the report, created as the file is read. If a word is not in the list, put it there. If it is$,$

increment a counter showing how many times the word has been used.

Definitions:

Word: Sequence of letters ending in a blank, a period, an exclamation point, a question mark, a colon, a comma,

a single quote, or a semicolon. You may assume that numbers do not appear in the words; they may be ignored.

Unique word: Words that are spelled the same, ignoring uppercase and lowercase distinctions.

Sentence: Words between end of markers.
