问如何在Qt中创建无符号数组队列？

EN

 QQueue<unsigned char> queue;
 queue.enqueue(65);
 queue.enqueue(66);
 queue.enqueue(67);
 while (!queue.isEmpty())
     cout << queue.dequeue() << endl;

class Queue
{
private:

    unsigned char buffer[SIZE];
    int readHead, writeHead;

    {
        readHead = writeHead = EMPTY;
    }

    void push(unsigned char data);
    unsigned char pop();
    unsigned char peek();
    bool isEmpty();
};

void Queue::push(unsigned char data)
{
    if((readHead - writeHead) >= SIZE)
    {
        // You should handle Queue overflow the way you want here.
        return;
    }

    buffer[writeHead++ % SIZE] = data;
}

unsigned char Queue::pop()
{
    unsigned char item = peek();
    readHead++;
    return item;

        return;
    }

    return buffer[readHead % SIZE];
}

bool Queue::isEmpty()
{
    return (readHead == writeHead);
}    

QQueue<unsigned char *> queue;
unsigned char *array1 = new unsigned char[10];    // array of 10 items
array1[0] = 65;
array1[1] = 66;
queue.enqueue(array1);
unsigned char *array2 = new unsigned char[20];    // an array of 20 items
queue.enqueue(array2);

unsigned char *arr = queue.dequeue();
qDebug() << arr[0] << ", " << arr[1];
