Function Name: catchyCounter

( char ) The filename of a text file containing lyrics to a song

( char ) A word/phrase to count

1. (double ) The number of times the word/phrase appears

Banned: fileread() and textscan()

Background:

You are starting a job as a songwriter for some of the music industry's biggest stars. But before you can write your first hit single, you need to figure out what makes a song catchy. You find that repetition can be very effective, so you decide to count the number of times a specific word/phrase appears in notoriously catchy songs.

Function Description:

Write a function in MATLAB that counts the number of times a certain word or phrase appears in a song's lyrics. The first input will be the filename of a .txt file that contains the lyrics to a song. The second input will be the word/phrase you are counting in those lyrics. Your function should output the total number of times that word/phrase appears in the .txt file, regardless of case.

Example:

beat_it.txt: Just beat it, beat it, beat it, beat it No one wants to be defeated Showin' how funky and strong is your fight It doesn't matter who's wrong or right Just beat it (beat it) 

>> num = catchyCounter('beat_it.txt','beat it') 

num = 6

Notes:

Because the phrase may be longer than one word, you should use strfind() . Also, the word or phrase that you are looking for might be a part of a larger word or phrase.

You do not need to check if a phrase occurs across multiple lines.
