优先队列C [英] Priority Queue C

问题描述

我正在尝试使用一个队列数组创建一个 priority队列，该数组的每个索引都是一个优先级.我尝试了以下解决方案，

I'm trying to create a priority queue using an array of queues, each index of the array being a priority. I tried the following solution,

队列数据类型包含一个数组llist，

The queue data type contains an array llist,

Queue *q_create(int size)
{
struct queue *p;
struct q_head *h;
int i;

if ((p = (struct queue *)malloc(sizeof(struct queue))) != NULL) {
    p->size = size;
    for (i = 0; i < PRIODIFF; i++) {
        h = &(p->llist[i]);
        h->head = NULL;
        h->tail = NULL;
    }
}
return p;
}

我对这行感到困惑: h =&(p-> llist [i]); 我当时在想 llist [i] = h .这是用C编写的另一种方式吗?我将其读取为 h = llist [i] 的地址.这是正确的吗?

I'm confused by the line: h = &(p->llist[i]); I was thinking that llist[i] = h. Is this another way of writing it in C? I'm reading it as h = the address of llist[i]. Is this correct?

谢谢

推荐答案

我正在读它，因为h = llist [i]的地址对吗?

I'm reading it as h = the address of llist[i] Is that correct?

是的
