| cppreference.com -> C++ Queues |
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 |
