Hello dear LEDA-newsgroup-user!
The user manual speaks about nil quite often.
(1) Is "nil" some LEDA-only construct, or is it in C++ standard/some C++
libraries?
(2) Does nil==NULL hold and does it always hold?
(3) Related question: can i write safely "if(node)" instead of
"if(node!=nil)" ?
Best regards,
thanks for replying,
Alex.
