How can I implement a queue in C++?

You can implement a queue in C++ using the STL queue class or by creating your own class. Which one would you prefer?

I'd like to create my own class. What should it look like?

You can start by defining a class with private members for the queue elements and a size variable. Would you like a sample code?

Yes, please provide a sample code for a basic queue implementation.

Here's a simple implementation:

class Queue {
private:
    int front, rear, size;
    unsigned capacity;
    int* array;
public:
    Queue(unsigned capacity);
    void enqueue(int item);
    int dequeue();
    bool isEmpty();
};

This defines a basic structure. Would you like to know more about the methods?
