个人作业三-ATM管理系统
一.题目要求
编写一个ATM管理系统，语言不限，要求应包括以下主要功能：
（1）开户，销户
（2）查询账户余额
（3）存款
（4）取款
（5）转账（一个账户转到另一个账户）
二.代码提交
1.头文件、结构体及函数定义
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define N 100
void Transaccount();//转账
void Menu(); //显示菜单
void Delete(); //删除
void Save_money();//存钱
void Withdraw_money();//取钱
void Show(); //查询信息
void save(int m); //信息存入文件
int read(); //读取信息文件
void Add();//增加开户
void Insert();//初始开户
struct Customer
{
char number[20];//身份证号
char name[10];//姓名
char cipher[20];//密码
float balance;//余额
}Customer[N],kong[2];
2.主函数与菜单
void Menu()
{
printf("ATM信息管理系统\n");
printf("***---------------------------***\n");
printf("1--转账\n");
printf("2--销户\n");
printf("3--存款\n");
printf("4--取款\n");
printf("5--查询账户余额\n");
printf("6--增加开户\n");
printf("7--退出系统\n");
printf("8--开户\n");
printf("***---------------------------***\n");
printf("请选择功能：\n");
}
int main()
{
int a;
do
{
Menu();
scanf("%d",&a);
if(a>8||a<0)
{
system("cls");
printf("输入错误！ \a\n");
continue;
}
system("cls");
switch(a)
{
case 1: Transaccount();break;
case 2: Delete();break;
case 3: Save_money();break;
case 4: Withdraw_money();break;
case 5: Show();break;
case 6: Add();break;
case 7: exit(0);break;
case 8: Insert();break;
}
}while(1);
}

void save(int m) /*保存文件函数*/
{ int i;
FILE *fp;
if ((fp=fopen("D:\\Customer_list.dat","wb"))==NULL) /*创建文件并判断是否能打开*/
{ printf ("cannot open file!\n");
exit(0);
}
for (i=0;i<m;i++) /*将内存中客户的信息输出到磁盘文件中去*/
if (fwrite(&Customer[i],sizeof(struct Customer),1,fp)!=1)
printf("file write error!\n");
fclose(fp);
}
int read() /*导入函数*/
{ FILE*fp;
int i=0;
if((fp=fopen("D:\\Customer_list.dat","rb"))==NULL)
{ printf ("cannot open file!\n");
exit(0);
}
