Question

银行账户管理系统 c语言

要求：
（1）需要处理的基础数据应包含
账号 用户姓名 电话号码 地址 余额 支出金额 存入金额
（2）用菜单选择并完成下述功能：
1各种基本数据录入
2各种基本数据修改
3各种基本数据插入
4各种基本数据删除
5基于各种数据查询
6基于各种数据的统计计算
7按余额进行排序
别写的太难 请最深使用 数组 结构体 指针 链表， 再难的就不要用了

我使用VC++ 6.0 编译 2楼的清屏clrscr() 会是error

还有 2楼 3楼的答案都没有实现 数据修改 插入 删除 以及排序功能

4楼同样没有实现 数据修改 插入 删除 以及排序

还有 此问题到29号我上交作业之前结束

Answer 1

如果你用VC编译，有几处警告，你可以把下面有双斜杠那一行去掉就行

通过VC++6.0编译

Answer 2

对楼上真的很无语，这样抄袭有意思吗？
程序已重新在vs2005和dev-c++下编译并通过，结果是正确的：
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<conio.h>

#define BUFFERSIZE 1024
#define MAXACCOUNT 1000
typedef struct BankAccount
{
int account;
int key;
char name[32];
float balance;
}BANKACCOUNT;

BANKACCOUNT accountCollection[MAXACCOUNT];
int curAccount = 0;

void InsertAccount(FILE *fp)
{
BANKACCOUNT newaccount;
printf("please input the account information\n");
printf(">>account num:");
scanf("%d",&(newaccount.account));
printf(">>key:");
scanf("%d",&(newaccount.key));
printf(">>name:");
scanf("%s",newaccount.name);
printf(">>balance:");
scanf("%f",&(newaccount.balance));
fseek(fp,0L,SEEK_END);
fprintf(fp,"%d %d %s %.2f\n",newaccount.account,newaccount.key,newaccount.name,newaccount.balance);
}
void GetAccount(FILE *fp)
{
int accountnum;
int key;
char name[32];
float balance;
int i =0,j;
char buffer[BUFFERSIZE];
int len;
curAccount = 0;
fseek(fp,0,SEEK_SET);
while(!feof(fp)) /* 因为feof()最后会读2遍，所以最后curAccount多加了1 */
{
fscanf(fp,"%d %d %s %f",&accountnum,&key,name,&balance);
accountCollection[curAccount].account = accountnum;

printf("account:%d\n",accountCollection[i].account);
printf("name:%s\n",accountCollection[i].name);
printf("balance:%.2f\n",accountCollection[i].balance);
}
}
int SearchAccount(FILE *fp,int accountnum)
{
int i =0;
for(i = 0;i< curAccount-1;i++)
{
if(accountCollection[i].account == accountnum)
{
printf("ACCOUNT[%d]:\n",i+1);
printf("account:%d\n",accountCollection[i].account);

}
return 0;
}
void DelAccount(FILE *fp,int accountnum)
{
int i;
if(SearchAccount(fp,accountnum)==0)
printf("Can't find the account\n");
else
{
for(i = 0;i<curAccount-1;i++)
{

fprintf(fp,"%d %d %s %.2f\n",accountCollection[i].account,accountCollection[i].key,accountCollection[i].name,accountCollection[i].balance);
}
printf("delete successfully!\n");
}
}

int main()
{
FILE *fp;
int accountnum;
int i;
do{
system("cls"); //清屏
puts("********************************************");
puts("* You can choose : *");
puts("* 1 : Insert a new Account *");
puts("* 2 : List all Accounts *");

switch(i)
{
case 1:
if(!(fp = fopen("account.txt","a+")))
{
printf("can't open the file account.txt\n");
exit(0);
}
InsertAccount( fp);

printf("press any key to continue.....\n");
getch();
fclose(fp);
break;
case 2:
if(!(fp = fopen("account.txt","r")))
{
printf("can't open the file account.txt\n");
exit(0);
}
GetAccount(fp);
ListAccount(fp);

printf("can't open the file account.txt\n");
exit(0);
}
GetAccount(fp);
if(!SearchAccount(fp,accountnum))
printf("There is not the account:%d\n",accountnum);

fclose(fp);
printf("press any key to continue.....\n");
getch();
break;
case 4:
printf("please input the account num:\n");
scanf("%d",&accountnum);
if(!(fp = fopen("account.txt","r")))
{
printf("can't open the file account.txt\n");
exit(0);
}
GetAccount(fp);
fclose(fp);
if(!(fp = fopen("account.txt","w+")))
{
printf("can't open the file account.txt\n");
exit(0);
}
DelAccount(fp,accountnum);
fclose(fp);
printf("press any key to continue.....\n");
getch();
break;

break;
}
}while(i != 5);
return 0;
}

这里账户数据文件名已经设定为account.txt，这个文件要和上面这个程序放在同一个文件夹下面，不然就得用绝对路径(比如"d:\\book\\account.txt")，account内容可以用记事本打开自己改动，然后运行程序后就可以在程序中添加或删除。account.txt一个参考内容如下：
1 10023 zhangsl 100.50
2 32001 sunq 5000.00
3 20010 wangxi 2500.00
