C :: How To Simply Input CSV File Into Universal Variable 2D Array

I am working in an assignment and part of this assignment is to input a CSV file with floats such as this:

8.5, 10.5, 90.5
49.5, 99 ,97
88, 70, 100
78, 2, 10

into an universal variable array.I just want to figure out a way to simply input the CSV file into a 2D variable array.The values in the array will be later use in functions that I'm trying to figure out but I can't do that until I store these values in the array. I think is just a matter of figuring out how to tell fscanf to ommit spaces and commas, but I don't know how. This is what I have done

Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
float grades[1001][101];
int main(int argc, char* argv[]){

[Code] ....

The output is this

Assignment 1 of student 1 = 8.5 Assignment 2 of student 1 = 10.5 Assignment 3 of student 1 = 0.0 Assignment 1 of student 2 = 90.5

I think I'm close to solve it but something is missing the output should look like this

Assignment 1 of student 1 = 8.5 Assignment 2 of student 1 = 10.5 Assignment 3 of student 1 = 90.5 Assignment 1 of student 2 = 49.5
