用户输入账号，然后对链表进行查找，要求用户输入账户密码，若匹配则可进行取钱（对余额做减法）。6、模拟存钱功能：struct account *saving(struct account *head,long account_num);与取钱类似，对余额做加法。7、排序功能：struct account *order (struct account *head); 根据账号对链表进行排序8、保存数据和读取文件功能：void save(struct account *head);save函数实现保存功能，退出程序时自动保存数据， 再次执行程序时自动从根目录中读取文件数据。三、调试过程中遇到的问题及解决方案一个比较大的问题就是文件的存储和读取问题，在存储和读取过程中会出现好多意想不到的错误，并且很难查找出来。存储相对比较容易实现，但是读取就比较困难，控制读取的结束就遇到了问题，试过好多方法，例如feof()函数，但是都不能解决问题，最后通过定义一个变量N计录账户数量，保存时将该变量N保存在文件的最开始，当读取是首先将这个变量N读取出来，然后用for循环通过N控制读取结束。 调试过程中还有好多小问题，基本都是由于马虎或者程序不够严谨造成的，这里就不一一列举了。#include #define NULL 0#define LEN sizeof(struct account) struct account long account_num;
