搭建链表，然后输出出来，出错了

Question

这个是什么问题啊，可以来帮帮我嘛，我搭建链表，尾插法搭建的，每一scanf输入，然后for循环输出出来，但是出错了

Answer 1

创建函数修改为：loand* Createlist2(loand *l,int n)
{
...........
return l;
}
主函数中调用：
int main()
{
loand* l;
l = Createlist2(l, c);
.........
}
修改如下，供参考：

#include <stdio.h>
#include <malloc.h>
typedef struct loand {
    int data;
    struct loand* next;
}Loand;

Loand * Createlist2(Loand * l, int n)
{
    l = (Loand*)malloc(sizeof(loand));
    l->next = NULL;
    Loand* r = l;
    for (int i = 0; i < n; i++)
    {
        Loand* s = (Loand*)malloc(sizeof(Loand));
        s->next = NULL;
        printf("请输入一个数:");
        scanf("%d", &s->data);
        r->next = s;
        r = s;
    }
    return l;
}
int main()
{
    loand* l;
    int c = 5, d;
    l = Createlist2(l, c);
    Loand* p = l->next;
    while (p)
    {
        printf("%d ", p->data);
        p = p->next;
    }
    return 0;
}
