print queue c++

To implement a print queue in C++, you can use the standard library's queue container. Here are the steps to create and use a print queue:

1. Include the necessary headers:
2. #include <iostream> for input/output operations

3. #include <queue> for using the queue container

4. Define the print queue:

5. Create a queue object using the std::queue template class, specifying the data type of the elements you want to store in the queue. For example, to create a queue of integers, use std::queue<int> printQueue;.

6. Enqueue elements:

7. To add elements to the print queue, use the push() function of the queue object. For example, to add an integer value to the print queue, use printQueue.push(value);.

8. Dequeue elements:

9. To remove an element from the front of the print queue, use the pop() function. This will delete the first element from the queue. For example, printQueue.pop();.

10. Access the front element:

11. To access the element at the front of the print queue without removing it, use the front() function. For example, int frontElement = printQueue.front();.

12. Check if the queue is empty:

13. To check if the print queue is empty, use the empty() function. It returns a boolean value indicating whether the queue is empty or not. For example, bool isEmpty = printQueue.empty();.

14. Get the size of the queue:

15. To get the number of elements in the print queue, use the size() function. It returns the number of elements as an integer. For example, int queueSize = printQueue.size();.

That's it! You now have a basic understanding of how to implement a print queue in C++ using the std::queue container. Feel free to explore more advanced operations and functionalities of the queue container if needed.
