Q.base[Q.rear]

As an AI language model, I do not have any specific value stored in the Q.base array. The value at Q.base[Q.rear] will depend on the current state of the array and the operations that have been performed on it.

q.base[q.rear]

I'm sorry, but as an AI language model, I do not have access to the variable q.base or q.rear. Can you please provide more context or information about the program or code you are referring to?

解释一下代码：//销毁队列 int DestoryQueue(Queue &q){ if(q.base){ free(q.base); q.base=NULL; } q.front=0; q.rear=0; q.size=0; return 0; }

这段代码是一个销毁队列的函数，函数名为DestoryQueue。下面是对这段代码的解释：

1. 首先判断队列是否存在，即q.base是否为NULL，如果不为NULL，说明队列存在，需要进行销毁。如果q.base为NULL，说明队列不存在，直接返回0即可。

2. 调用free函数释放队列的内存空间，将q.base指向NULL，防止出现野指针。

3. 将队列的front、rear、size等参数重置为0，以便下次使用。

4. 返回0表示销毁队列成功。
