colon operation

Are you sure this is not a typo and it should be the conditional operator?
ilist_item *next = _current << _current **?** _current->next() : _current;That does not look correct either, but it depends on the code, i.e. if_current != NULLgo to the next node, otherwise returnNULLOf course I could be wrong:-O

I don't know if it is right I only got it from a book "C++ Primer 3rd" It is in sector 5.11.1 :(

I assume the book is:- http://www.awprofessional.com/catalog/product.asp?product_id={B668B50F-696A-4219-8ABD-BEDA96CBC10A}&session_id={50C3D76B-22C3-4D54-83E3-7117D77DADEE}[^] try the errata section, but waut a while someone clever than me may have the definitive answer!

Yes It is Only my book is translated into chinese. Those code may be found in A Linked List Example of chapter 5 Statements Great! Thanks!!!

it is accessing the constructor (maybe) of that object. My God is more powerfull Than Your God. (the line that divides the world)
The code is extracted from the function below: inline ilist_item* ilist:: next_iter() { ilist_item *next =_current <<_current = _current->next() :_current; } Mavbe the right is as Mr. Ted Ferenc said: inline ilist_item* ilist:: next_iter() { ilist_item *next =_current ? _current = _current->next() : _current; } Do you think so? Thanks for your answer!!! Happy 2004!!!

I can't say 100%, the simple test is to try and compile the code and step through using the debugger. What I think it is, is a class to iterate through a linked list, where _
currentis the current node,next_item()checks if_currenthas been defined is so get the next node, otherwise return_current, which I asuume isNULLIsn't C++ fun!

ilist_item *next = _current << _current = _current->next() : _current; I don't know the meaning of the above sentence extracted from book "C++ primer 3rd" Could somebody tell me its meaning? Thanks in advance!
You know.. that subject line sure looked suspicious for a forum like this. :rolleyes: -- They say the most horrible things, but I hear violins. When I close my eyes, I'm at the center of the sun.

True. I figure this forum can only treat missing semicolons and related issues. ;) -- They say the most horrible things, but I hear violins. When I close my eyes, I'm at the center of the sun.

Yeah! C++ is very fun and it is abundant in perfect thinking!
