From an entire paragraph entered by the user, we want to find out if a particular word, of the users choice, can be found in that paragraph and at what frequency.

Your job will be to step through the paragraph looking for a match of the word provided by the user, counting each match. The words should match regardless of capitalization or punctuation (i.e., FRIEND, Friend, and Friend! should all match to the word Friend).

1. Do not use the string class instead use arrays of characters with cstrings

2. You can only use strlen from cstring library
