Hi friends!!

I have typed in a function, but it shows declaration error.

This is just the fragment of the program i have typed in..
Kindly assume that all header files and class declarations have been included..

I have tried to write void club:: writeinto() but the error still persists..

What I have tried:

here is the function:

C++

void writeinto()
{
    club c;
    int N,i;
    {
        ofstream fout("project.dat",ios::binary);
        {
            if(!fout)
            {
                cout<<"Error";
                exit(0);
            }
            while(!fout.eof())
            {
                cout<<"Enter the number of records to be entered";
                cin>>N;
                {
                    for(i=0;i<N;i++)
                    c.enterdata();
                    fout.write((char*)&c,sizeof(c));
                }
                fout.close();
            }
        }
    }
}

What is the error?

Where is the definition of club? Please show the code that is related to the problem, and the exact error message.

Thanks a lot Rick.. But my compiler shows declaration syntax error in the bool declaration. I have not done bool at school, so i have no idea about it.. Or is the problem with my compiler?

So, change it to void and remove the return statement at the end.

I have no idea why a c++ compiler would not accept a bool type for a function. It really isn't necessary so try what Dave recommended.

I edited your question and moved the code to the "what I've tried" section and added some indentation that was either lost or non-existent. It seems there is a missing curly brace at the end. Also, some of the the other braces are unnecessary.

Here is a revised version with some of the braces eliminated and the spacing adjusted. It also returns a boolean variable to indicate whether it worked or not.

By the way, I have never written code that checks for EOF on writing. Unless you have a fixed length file that can never grow I don't think it will ever happen. For this reason I have commented it out.

C++

bool writeinto()
{
    club c;
    int N,i;

    ofstream fout( "project.dat", ios::binary );
    if( ! fout )
    {
        cout<<"Error";
        return false;
    }
//  while( ! fout.eof() )
    {
        cout << "Enter the number of records to be entered";
        cin >> N;
        for( i = 0; i < N; i++ )
        {
           c.enterdata();
           fout.write( (char*)&c, sizeof(c) );
        }
        fout.close();
    }
    return true;
}
