Ok, I'm fairly proficient with C++ but I have limited experience with the STL. I'm writing something to a spec and I've been told I *must* use the STL queue to store some objects. So far, so good. However, am I right in thinking that I can't traverse the queue without destroying it!? How am I supposed to print it like the spec dictates? I'm confused, especially as it seems there's no std::queue<t>::iterator for me to play with. So, where I'm at now:

while(!incomingPackets.empty())
{
    std::cout << (*(incomingPackets.front()));
    std::cout << std::endl;
    incomingPackets.pop();
}





The second time that's called, it fails an assert after the first object is printed! [bawling] [Edited by - zdlr on August 21, 2005 6:34:47 PM]

Double-check whether you've been told to use std::queue or std::deque.
'deque' stands for "double-ended queue", and is traversable.
std::queue is an adaptor, providing a pure queue interface for another container - usually std::deque.

The firewall class should store both incoming and outgoing network packets in queue structures


Ignore mentions of 'firewall' and 'network packets' - it's just a firewall simulation that does nothing with real network packets. It's merely an exercise in class design, etc.

I'd be prepared to use a deque if I'd be allowed to iterate over it, it hardly seems mission critical that it uses queue structures exclusively.
