Declaration Error, C++

[Kindle Life 123]

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

here is the function:

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 was the error?

I assume you have #included declarations for club, iostream.

and you are using namespace std.

My compiler is turbo c++ 4.5. So it runs without namespace std.
the error is not specified.
Should I include void club::writeinto()?

Thanks a ton for all your efforts...
