Help reading csv file

[Greenfractallines]

Hello, so I'm trying to read in a csv file but running into a lot of errors bugs.

The file format (obviously) is something like

1.4, 3.4, 6.7,
4.3, , 7.6

The blank bit on the second line is whitespace, but I still want to read it as I'm storing the read in data as strings and extracting data later.

I've tried this line of code

string line;
getline(FILE,line);
istringstream s(line);
string field;
getline(s,field,',');
cout << field << endl;

but this just gives out the first numbers in the columns & I don't know why.I thought that getline(s,field,','); would read up to the comma and then keep reading until the end of the line

I thought that getline(s,field,','); would read up to the comma

Yes

and then keep reading until the end of the line

It leaves the rest in input stream for subsequent reads.
Use getline in a loop to read all values:

istringstream s(line);
string field;
while(getline(s,field,','))
    cout << field << endl;

I'd sorted this out anyway but that's what I did. Cheers =D
