怎么连？要变成链表吗？
#include "stdio.h"
#include "malloc.h"
#define LEN sizeof(struct user)
#define NULL 0
int n = 0; //全局变量最好在这里初始化
// int num,shouzhi;
// char menlei[40];
// char shijian[15]; //这句感觉没有用处
struct user
{
int num;
int shouzhi;
char menlei[40];
char shijian[15];
struct user *next;
};
struct user *creat(void);
void main()
{ // 我想你是想知道怎样在main里用你的链表吧！
int i = 1;
struct user *head;
struct user *p;
head = creat();
p = head;
while(p)
{
printf("第%d :\n", i++);
printf("用户账号: %d\n", p->num);
printf("收支: %d\n", p->shouzhi);
printf("门类: %s\n", p->menlei);
printf("时间: %s\n", p->shijian);
