What are the fundamental operations of a C++ queue?

Basic operations of a C++ queue include:

1. Create a queue: Create a queue object using the queue class from the Standard Template Library (STL).
2. #include

   // Create a queue object
   std::queue myQueue;

3. Enqueue operation: Adding an element to the end of the queue. This can be achieved by using the push() member function.
4. // Adding elements to the queue
   myQueue.push(10);
   myQueue.push(20);
   myQueue.push(30);
5. Dequeue operation: Remove an element from the head of the queue. You can use the pop() member function to implement the dequeue operation.
6. Dequeue operation: myQueue.pop();
7. Accessing the first element of the queue involves retrieving the element at the front of the queue without removing it. This can be achieved by using the front() member function.
8. Access the first element in the queue and assign it to the variable frontElement.
9. Accessing the back element: Retrieve the element at the end of the queue without removing it. You can use the back() member function to access the back element.
10. Get the last element in the queue.
11. To check if the queue is empty, you can use the empty() member function.
12. // Check if the queue is empty
    if (myQueue.empty()) {
    // The queue is empty
    } else {
    // The queue is not empty
    }
13. You can get the number of elements in the queue by using the size() member function.
14. Calculate the number of elements in the queue by obtaining its size.

These are the basic operations of a C++ queue, which can be used as needed to implement queue functionality.
