Searching parallel arrays

[rangerSkip]

My program is designed to take input from a file containing a list of titles and authors. The file looks like so:

title
associated author
next title
associated author
etc.

The problem I'm having is with my showBooksByTitle and showBooksByAuthor functions, I guess what I'm asking is how does one compare parts of strings so that if a user searched for Mal (and there was author D.S. Malik and just Malik) both would show up?

right now this code returns only exact matches and also prints an empty newline and a new line with some spaces and a ().

Of course any help is greatly appreciated. This is my first year programming. I've included the whole code just to be safe that I'm not leaving out anything that could be the problem.

You are using C++ string objects. If your string name contains "Mickey Mouse" then string::find() should locate "key".

Thank you so much! I was using that operation but I had it backwards.
