What is a queue library in C++?

Can you explain what a queue library is in C++?

A queue library in C++ provides data structures and functions to manage a collection of elements in a first-in, first-out (FIFO) manner.

What are some common use cases for queues in programming?

Queues are commonly used in scenarios like task scheduling, managing requests in web servers, and handling asynchronous data.

How do I implement a simple queue using the C++ Standard Library?

You can use the std::queue class from the <queue> header. Here's a simple example: std::queue<int> q; q.push(1); q.push(2); int front = q.front(); q.pop();.

Are there any performance considerations when using queues?

Yes, performance can vary based on the underlying data structure. For example, using a linked list can be more efficient for dynamic sizes compared to an array.
