Introduction to the programming project. Stuck while creating data file from table

I have been provided with a project for the class and am stuck on its parts. The project has this table:

enter image description here

How can I create this information in a serial file for reading into a C ++ program? It looks like it will be a three-dimensional array. Am I looking too much into this?

It depends on what you are trying to do. Usually, if you are just trying to read it, you can save it as a flat file. With flat files, you usually have two common formats for fixed length recording or a comma separately (there are other flat file formats that you can implement, but these are two common fomats).
