Strange ifstream problem...

I have the following code:

Code:

---

#include <iostream>
#include <fstream>
using namespace std;

char academics[1000000];
char sports[1000000];
char extra[1000000];
char id[20];
bool loggedIn=0;




int main()
{
        do{
                        cout<<"Enter ID Number"<<endl;
                        cin>>id;

                                if (id=="04390") {
                                loggedIn=1;
                                break;
                        }else{
                        //repeat above for all other valid id numbers, sort of a catch all so that a slipped finger doesn't make their portfolio unviewable through the viewer.html construct...
                                loggedIn=0;
                                break;
                        }
        }while (loggedIn==0);
        //read files into strings....

        //note that, when using for real project...use fin("f:\\users\\whatever double slash"id"double slash academics.portfolio)...
       
        ifstream afin("c:\\drew\\ElectronicPortfolioFiles\\academics.portfolio");
        if (!afin.is_open) {
                cerr<<"Error Opening File: 'academics.portfolio'"<<endl;
                cerr<<"Make Sure The File Exists And Is In Your ID Folder"<<endl;
                exit(1);
        }
        afin>>academics;
        afin.close();

        ifstream sfin("c:\\drew\\ElectronicPortfolioFiles\\sports.portfolio");
        if (!sfin.is_open) {
                cerr<<"Error Opening File: 'sports.portfolio'"<<endl;
                cerr<<"Make Sure The File Exists And Is In Your ID Folder"<<endl;
                exit(1);
        }
        sfin>>sports;
        sfin.close();

        ifstream efin("c:\\drew\\ElectronicPortfolioFiles\\extra.portfolio");
        if (!efin.is_open) {
                cerr<<"Error Opening File: 'extra.portfolio'"<<endl;
                cerr<<"Make Sure The File Exists And Is In Your ID Folder"<<endl;
                exit(1);
        }
        efin>>extra;
        efin.close();
        char fileExtension[]=".xml";
        char* fileName=strcat(id,fileExtension);


                ofstream fout(fileName);
                if (!fout.is_open) {
                        cerr<<"Error Compiling Portfolio, Sorry For The Inconvenience."<<endl;
                        exit(1);
                }
        fout<<"<?xml version='1.0'?>"<<'\n'<<"<!DOCYPE portfolio ["<<'\n'<<"<!ELEMENT portfolio (academics, sports, extra)>"<<'\n'<<"!ELEMENT academics (#PCDATA) >"<<'\n'<<"!ELEMENT sports (#PCDATA) >"<<'\n'<<"!ELEMENT extra (#PCDATA) >"<<'\n'<<"<portfolio>"<<'\n';
        fout<<"<academics>"<<'\n'<<academics<<'\n'<<"</academics>"<<'\n'<<"<sports>"<<'\n'<<sports<<'\n'<<"</sports>"<<'\n'<<"<extra>"<<'\n'<<extra<<'\n'<<"</extra>"<<'\n'<<"</portfolio>";
        fout.close();


        return 0;
}

upon compiling, i receive the following error:
member function must be called, or it's address taken in function main()
it says that error occurs on a few lines, each happens to be one where i use the ifstream operator....whats up with this code?

I tried to compile your code and got 4 errors, all the same.
It's because of the is_open. This is a function and not a variable.
Change it to:

Code:

---

if( !sfin.is_open() )

---

oh man!
I've used that code a dozen times before, i can't believe i screwed that up! That will teach me to write code on the back of a electrical schematic during breaktime...anyhow thank you very much, i probably never would have caught that. :)

There's where I'm undecided aobut C++. You can add a lot of structure, but then you get problems like that!
