What are some examples of circular queues in C++?

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

A circular queue is a linear data structure that follows the FIFO principle but connects the end back to the front, forming a circle.

What are some practical examples of using circular queues?

Circular queues are often used in scenarios like CPU scheduling, buffering, and managing resources in a circular manner.

Can you show me a simple C++ implementation of a circular queue?

Sure! Here's a basic implementation:

class CircularQueue {
private:
    int *queue;
    int front, rear, size;
public:
    CircularQueue(int s) : size(s), front(-1), rear(-1) {
        queue = new int[s];
    }
    // Methods for enqueue, dequeue, etc.
};

This initializes a circular queue with a specified size.

What are the advantages of using a circular queue over a regular queue?

Circular queues utilize space more efficiently by reusing empty slots, preventing wastage of memory that occurs in regular queues.
