Difficulties in Reading Text File and Organizing Output

jesseb96 (10)
Hi everyone! I'm fairly new to programming, and I'm having difficulties on an assignment that was given by my professor.

I'm trying to have the program read a text file, and produce an output sorted alphabetically. I would also like to place the texts in proper columns to be organized, although I'm having difficulties with both of these tasks. Even when using setw I haven't been able to fix the offset of the output. The professor has not put much content to assist us in the program or the concepts involving it, making this even more difficult. All help would be welcomed and greatly appreciated.

The sample output the teacher posted was this. I'd rather have it organized columns, and figure out more creative ways to make it look neater.

LastName FirstName DaysofRental BalanceDue
Anderson Paul 30 20.00
Doe John 10 95.20
Foster Sam 30 15.00
O'Donell Miriam 10 24.30
Smith Joe 15 100.50
Total Balance Due for file: 255.00
Customer with the highest number of rental days are : Paul Anderson, Sam Foster
Customer with the highest balance due are: Joe Smith

He didn't ask you to make it pretty, don't spend your time on homework on prettyness until after you get the work done as assigned.
