Java中的类,对象和实例是什么？

这是C编程语言中链表的代码.

#include <stdio.h>    /* For printf */
#include <stdlib.h>   /* For malloc */

typedef struct node {
    int data;
    struct node *next; /* Pointer to next element in list */
} LLIST;

LLIST *list_add(LLIST **p, int i);
void list_remove(LLIST **p);
LLIST **list_search(LLIST **n, int i);
void list_print(LLIST *n);

代码没有完成,但我认为这对我的问题已经足够了.这里在结构节点的末尾使用"LLIST",它也用作函数原型的返回类型list_add.到底是怎么回事？

我不知道如何解决这个问题.请看一下,如果可能的话,让我如何解决它.这是我的pom.xml文件.

有人可以解释一下吗？

struct node 
{ 
    int data; 
    struct node * link; 
} 
main() 
{
    struct node *p, *list, *temp; 
    list = p = temp = NULL; 
    ......................... 
    ......................... 
} 

addbeg() 
{ 
    int x;
    temp=malloc(sizeof(struct node));
    scanf("%d", &x); 
    temp->data=x;
    temp->link = list;
    list=temp;
}

这是一个通过C语言在链表中输入数据的代码.代码不完整,但我认为它足以达到目的.请解释基本上这些代码的编码:

 temp=malloc(sizeof(struct node));

和

 temp->link = list;
 list=temp;.
