Hi
On a related subject, what are the rules for initializing const members
outside the class definitions? My C++ books don't cover that very well
;-)
E.g.
class myclass : public TObject {
public:
const Int_t count;
...
}
The following doesn't compile:
myclass::myclass(Int_t newcount){
count=newcount;
}
I thought you got once chance to initialize a const, and that the
constructor may be the place to do it, but this is obviously not the
case :-)
Cheers!
