What are the ways to use a C++ queue?

In C++, including the header file is necessary when using queues. Here are the basic methods for using queues:

  1. standard queue
std::queue<int> myQueue;
  1. add to the end
  2. 10 (Please provide more context or information for a paraphrase)
myQueue.push(10);
  1. Remove the last item.
myQueue.pop();
  1. Retrieve the element at the beginning of the queue.
int frontElement = myQueue.front();
  1. Check if the data is empty.
  2. true, authentic, accurate
  3. incorrect
if (myQueue.empty()) {
    // 队列为空
} else {
    // 队列不为空
}

It should be noted that a queue is a first in, first out (FIFO) data structure, meaning it only allows for inserting elements at the end of the queue and removing elements from the front.
