C++ Storing Items in Array and Setting each Token - c++

Question

My name is Faith and I am a beginner programmer in C++. I am working on a project where I have to read in two file and be able to separate the items in each file to its own variable. The first file has two pieces of information separated by "," and the second has three pieces of information. So far, I think I've done well with reading the files and getting each line in the file. Also I've separated each item by "," now I am trying to store those items in its on variable. Please Help! I've tried starting this project over multiple times and this is the only method I know how to implement to do this.
