Hey Guys, Im working on some homework and need some help

We have 2 CSV Files that we will be working from

One file has the Name of student, and courses hes taken

The other file has Class To Be Taken, and Prerequisites

Basically What I need to do is

If the First File has

Bob, A, B, C

and in the second file

D, A, B,C

I would output, Bob Took A, B, C

and Bob is Eligible for D

I am supposed to use Data Structures so what would be the best way to get started in this

So far in my program ive read in both files just using file input and strtok to separate stuff up

Current output looks something like this:

Eric took MATH 1426, CSE 1310, CSE 2315, CSE 1320,

and is eligible for
