How to read and use data from CSV files? [duplicate]

Question

I have CSV files that contain 2 columns of x and y coordinates, that are the positions of particles.

I want to read these files and be able to use the data inside to calculate a function (I mean I want use the coordinates to calculate the pair distribution function g(r)).

I have the algorithm to calculate this function but I need help with how to access the CSV files, and be able to read and use the data inside. I'm new to programing in C, can anyone help?

Are those coordinates in integer or float format? Can you copy and paste a couple of lines? It's very easy to read a CSV file but need to know if its integer or float data. See fscanf which allows you to read formatted data from a stream/file. — ja_mesa

You use a library, such as libcsv.
