Reading in input from file

I have data like this in a text file

A 2 B F
B 1 E
E 0
F 3 A B E

The first is the vertex name...so A in the first line
The second is the # of vertices it is connected to (out-degree)...so 2
Everything after the integer needs to be added to a linked list...the vertices that A is connected to... B->F will be what the linked list looks like for A.

Keep in mind the adjacent vertices list isn't fixed...it can be empty as seen for E or it can go to 100...or beyond.

I have this for reading in the input...I'm using an array of structs...but I'm stuck on the linked list part since it isn't fixed.

Code:

---

                ifstream fin;
        fin.open("table.txt");
       
        int i = 0;
        while(!fin.eof()){
               
                fin >> Gtable[i].name >> Gtable[i].out_degree >> Gtable[i].list.addFront(); // stuck here...the parameter in addFront should be the char that is read in.

               
                ++i;
        }
        fin.close();

You should read the every whole line of your file in some std::string bufer (do it in a loop). Then parse the line depending of the value of its second field (how many fields are there till the end of line)
