好的,这是一个求链表中最大值节点的代码框架,需要补充max_node函数的实现。下面是完整代码:
```c
#include <stdio.h>
#include <stdlib.h>
struct node {
int val;
struct node* next;
};
struct node* setlink(int N);
int max_node(struct node* head);
int main() {
int N;
struct node* head;
scanf("%d", &N);
head = setlink(N);
printf("%d", max_node(head));
return 0;
}
struct node* setlink(int N) {
struct node* head = NULL;
struct node* cur = NULL;
for (int i = 0; i < N; i++) {
int val;
scanf("%d", &val);
struct node* newNode = (struct node*)malloc(sizeof(struct node));
newNode->val = val;
newNode->next = NULL;
if (head == NULL) {
head = newNode;
cur = head;
} else {
cur->next = newNode;
cur = newNode;
}
}
return head;
}
int max_node(struct node* head) {
if (head == NULL) {
return -1;
}
int maxVal = head->val;
struct node* cur = head->next;
while (cur != NULL) {
if (cur->val > maxVal) {
maxVal = cur->val;
}
cur = cur->next;
}
return maxVal;
}
```
其中,setlink函数用于建立链表。max_node函数用于查找链表中的最大值节点。在main函数中,先输入链表的长度N,然后调用setlink函数建立链表,并将链表头节点传入max_node函数中进行查找。最后输出最大值节点的值。
