一、 定义结构体
#include"stdio.h"
#include"iostream"
#include"string.h"
#include<windows.h>
using namespace std;
int num=0;
struct Login{//登录结构体，有用户名和密码
char username[10];
char password[10];
}lg[100];
struct Customerinfo{
char idcard[10];
char cuname[20];
char cupwd[10];
char cuaddr[30];
char phone[11];
float total;
}customer[100];
struct record{
char idcard[10];
char date[12];
char category[8];
float number;
char Handler[20];
}dwrecord[1000];二、实现系统登录功能
int SystemLogin(char *uname,char *pword){//系统登录功能
FILE *fp;
int i;
if((fp=fopen("login.txt","r"))==NULL){
printf("文件打开失败！\n");
return 0;
}
for(i=0;!feof(fp);i++){
fscanf(fp,"%s%s",&lg[i].username,&lg[i].password);

printf("-- 2.存储 3.取款 --\n");
printf("-- 4.存款查询 5.取款查询 --\n");
printf("-- 6.显示信息 7.删除信息 --\n");
printf("-- 8.修改信息 9.存取款统计 --\n");
printf("-- 10.客户存取款排序 --\n");
printf("------------------------------------------------\n");
printf("请输入您的选择(0-10)\n");
