这个函数有错么？？？？怎么改？？？
int Locate(NODE *head, NODE *data){
    NODE *p;
    int n;
    for (p = head, n = 0; p->link != NULL;){
        if (strcmp(p->name,data->name))return n;
        else p = p->link; n++;
    }
}
目的：查找链表中元素，并输出所在位置

如果没错的话那是不是调用的语句错了？？？下面是完整代码

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
typedef struct node{
    char name[20];
    struct node *link;
}NODE;
void creat(NODE *head, int n){
    NODE *p;
    for (; n > 0; n--){
        p = (NODE *)malloc(sizeof(NODE));
        gets(p->name);
        p->link = NULL;
        head->link = p;
        head = p;
    }
}
void output(NODE *head){
    NODE *p;
    p = head->link;
    while (p != NULL){
        puts(p->name);
        p = p->link;
    }
}

int Locate(NODE *head, NODE *data){
    NODE *p;
    int n;
    for (p = head, n = 0; p->link != NULL;){
        if (strcmp(p->name,data->name))return n;
        else p = p->link; n++;
    }
}

void main(){

    NODE *head;
    int n;
    head = (NODE *)malloc(sizeof(NODE));
    head->link = NULL;

    printf("结点个数为:");
    scanf("%d", &n);
    getchar();
    creat(head, n);
    printf("\n\n");
    printf("输出;\n");
    output(head);

    NODE *p;
    p = (NODE *)malloc(sizeof(NODE));
    printf("请输入要查找的数据：");
    gets(p->name);
    printf("所在位置为：%d", Locate(head, p));
}

我们学校刚讲完链表，让用链表练习，，，，求解

加了，程序还是有问题呀
