What are the ways to use a C++ queue?
In C++, including the
- standard queue
std::queue<int> myQueue;
- add to the end
- 10 (Please provide more context or information for a paraphrase)
myQueue.push(10);
- Remove the last item.
myQueue.pop();
- Retrieve the element at the beginning of the queue.
int frontElement = myQueue.front();
- Check if the data is empty.
- true, authentic, accurate
- 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.
