Creating "Library" Program

[ThacZero]

I am writing a program that stores file.txt strings into parallel arrays.
Once I have my arrays, create a loop that prompts the user for these following input commands:

Show: Prints arrays to the screen.

Author: User inputs author name, loop searches author array for input author name then prints book title and author name, as well as the total number of books found.

Title: User inputs title name, loop searches title array for input title name then prints book title and author name, as well as the total number of books found.

Quit: Exits program.

So here is where I am hung up. When the user goes to input author / title name, and the line includes spaces, the program goes bonkers. To fix that I tried using getline in my if statements but they werent working for some reason. Also the text file I am reading from has one author name listed in different ways.
example: Tolkien
J.R.R Tolkien

I want the search author function to find both books even if my user inputs
'tolkien'.

So:
1. Why am I having trouble using get line in my if statements?
2. How do I search array indices for a particular string?


Thanks.
