c++ queue

To use a queue in C++, you first need to include the header file. Then, you can declare a queue using the syntax: queue queueName; To insert an element into the queue, use the push() method: queueName.push(value); To access the front element in the queue, use the front() method: queueName.front(); To remove the front element from the queue, use the pop() method: queueName.pop(); To check if the queue is empty, use the empty() method: queueName.empty();
