In c++ and using binary trees

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 1. 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.
