The C++ Queue is a container adapter that gives the programmer a FIFO (first-in, first-out) data structure.
back() | returns the last element |
empty() | true if the queue is empty |
front() | returns the first element |
pop() | removes the first element |
push() | adds an element to the end of the queue |
size() | returns the number of elements in the queue |
