Explore the STL queue, a container adapter that implements a first-in, first-out queue based on another container.
- [Instructor] A queue is a container adaptor…which is like a wrapper that uses an underlying container…to hold its contents.…The queue implements a first in first out queue…where elements are pushed onto the back of the container…and then popped from the front.…Here I have a working copy of queue.cpp…from chapter two of the exercise files…and you'll notice that I include the queue header…which contains the queue type.…I'm also including the deque and list headers…because we're going to use those as underlying containers.…
Here we're creating a queue from a list…using the list as the underlying container.…So first I create a list and I initialize it…with an initializer list and then I construct a queue…from that list and so I list as the two parameters…to the template for the queue an integer type…and a list of integers type.…And then I pass the list to the constructor…and this constructs the queue.…And then I call report queue and report queue…just reports the size and the front and the back…because the queue is not a random access container…
