QOTD
-
Congrats to Christian Graus for thinking up the QOTD. I believe this is the first one I've seen from a CPian. Of course, I can't answer because I haven't a clue when it comes to STL. So I'll just leave the answering of it to the rest of you. :) David Stone It seemed similar to someone saying, "Would you like to meet my knife collection?" Ryan Johnston on Elaine's sig

That's not really Christian. That's his alter ego, Grausman, posing as him. When it comes to STL... The Grausman codeth. :) *He should get it if he reads this message. Jeremy Falcon Imputek "C# is the answer to a question nobody asked." - Chris Losinger

i don't even see what i'd call the "correct" answer :( -c

Well it has to be C or D right? I mean, I read the "Pointers" section in Inside C# so I know what a pointer is. So shouldn't it be C or D? David Stone It seemed similar to someone saying, "Would you like to meet my knife collection?" Ryan Johnston on Elaine's sig

it's probably D. but, i've found that i'll run into trouble unless i do it like this: (*it).Foo(); in C, the precedence of "." is higher than that of "*", so *it.Foo() means *(it.Foo()), which is usually illegal. the parens forces the dereference to happen first. -c

Why not it->Foo(); Joel Lucsy (jjlucsy@ameritech.net)
heh. :) yeah, i guess that would work, too. but, i've honestly never seen that in any live code or example: it's always (*it).Foo(); -c

I don't know anything about STL, what is an STL iterator? Having said that the only option that look reasonable is D (although other options are possible if iterators have overloaded operators). Ryan Johnston

Wow, interesting... I guess the only difference is one keystroke, but I am just surprised. What kind of programming do you do? Ryan Johnston

there's probably some deep metaphysical reason why people want to use (*it). instead of it-> . i just do it because that's how i learned it. Ryan Johnston wrote: What kind of programming do you do? a little of everything, but mostly 2d graphics. -c

The answer is C) (*it) is the value, so &(*it) is the address of the value. Or did I miss something? I vote pro drink :beer:

Looking into the MSDN can open eyes! iterator overloads operator*. plain and simple. Somehow the STL trys to use references wherever possible.
