Quick question - in one of the examples in the Dr.Dobbs article, he does this:
1 2 3 4 5 6 7 8
r = n; // won't work!
I can't compile this, I get an error:
uninitialized reference member `C::r'
pointing to the int &r;...
Even after removing the line he says won't work, I still get a compiler error. To me, it doesn't make sense to do int &r;... Not sure what I'm looking at there (declaring an address of something that is an integer?).
