Reading Data and printing arrays

[Zakronz]

I am very new to C++ and have been given a few tasks for my internship, the end product being a functional app of some sort that graphs information (such as the point of intersection) of two scatter plots. The first step is to design some simple code that reads data from a .txt file and then prints the arrays to screen. I can write code which opens the data file no problem. But I need only the information, and printed to screen as a series of data points (x, y). Any help on how to get this started would be greatly appreciated.
Thank You.
