I am making a game-type program similar to the idea of pokemon. We have a tournament class that keeps track of several teams(its own class) which consists of pets(its own class) with different kinds of pets being subclasses of CPet.
We are attempting to pass a file name into main, from main pass that file name into the Tournament class. In the Tournament class we open the file with:
14 //Construct a tournament
15 CTournament::CTournament(const char *Filename){
16 //opening file
17 ifstream inFile(Filename, ios::in);
18 if(inFile.bad()){
19 cout << "File error" << endl;
20 return ;
21 }
22 //get Teamlist for tournament
23 while(!(inFile.eof())){
24 CTeam* temp = new CTeam;
25 temp->ParseTeam(inFile);
26
27 TeamList.push_back(temp);
28 }
29 }
Here we pass inFile into CTeam.ParseTeam which looks like:
30 void CTeam::ParseTeam(std::istream in){
31 string readline;
32 getline(in, readline);
33 this->TeamName = readline;
34 while(!(in.eof())&&(readline != " " || readline != "/n"))
35 {
36 getline(in, readline);
37 this->Parse(readline);
38 }
39 }
and we are getting the error:

I know there is a similar question about this where he did not include fstream. We have included it in both header files.
I thought maybe it was a problem of not passing the correct type into PraseTeam, but I could not find anything very specific on how else to pass the file into ParseTeam to verify whether I was doing it correctly or not.
Thanks in advance.
You need to pass the stream by reference, because streams are not generally copyable:
void CTeam::ParseTeam(std::istream &in)
