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）等...
允许网上查询参考，但请注意不要直接抄袭，可以理解看懂别人的代码，再自己编写
函数说明
账户结构体
typedef struct //定义账户结构体
{
int id;
int password;
float money;
}account;
创建账户
void create(account user[],int n) //创建账户
{
user[n].id = user[n - 1].id + 1; //自动生成用户卡号
printf("卡号为：%d\n", user[n].id);
printf("请输入密码：");
scanf_s("%d", &user[n].password);
user[n].money = 0; //初始化存款为0；
}
注销账户
int cancel(account user[], int n) //注销账户
{
int cancelid, cancelpw;
printf("请输入需要注销的账号：");
scanf_s("%d", &cancelid);
for (int i = 0; i <= n + 1; i++)
{
if (user[i].id == cancelid) //寻找需要注销的账户
{
for (int j = 0; j != 1;)
{
printf("请输入密码：");
scanf_s("%d", &cancelpw); //密码匹配
if (user[i].password == cancelpw)
{
user[i].id = 0; //重置账户状态
user[i].password = 0;
user[i].money = 0;
printf("销户成功！\n");
return 0;
}
else
{
printf("密码错误！\n"); //输错密码提示及反馈
printf("是否重输密码？Y/N\n");
char flag;
scanf_s("%c", &flag, 1);
if (flag == 'n' || flag == 'N') return 1;
}
}
}
}
}
查询余额
int query(account user[], int n) //查询余额

char flag;
scanf_s("%c", &flag, 1);
if (flag == 'n' || flag == 'N') return 1;
}
}
}
}
}
存款函数
int save(account user[], int n) //存款函数

if (user[i].password == savepw)
{
printf("请输入存款数额：\n");
float addmoney;
scanf_s("%f", &addmoney);
user[i].money += addmoney; //将存入钱款加入存款中
printf("存款成功！，当前余额为：%f", user[i].money);
return 0;
}
else
{
printf("密码错误！\n");
printf("是否重输密码？Y/N\n");
char flag;
scanf_s("%c", &flag, 1);

取款函数
int draw(account user[], int n) //取款函数
{
int drawid, drawpw;
printf("请输入需要取款的账号：");
scanf_s("%d", &drawid);

printf("请输入密码：");
scanf_s("%d", &drawpw);
if (user[i].password == drawpw)
{
printf("请输入取款数额：\n");
float addmoney;
scanf_s("%f", &addmoney);
user[i].money -= addmoney; //将存款中的取款金额减去
printf("取款成功！，当前余额为：%f", user[i].money);
return 0;
}
else
{
printf("密码错误！\n");
printf("是否重输密码？Y/N\n");
char flag;
scanf_s("%c", &flag,1);
if (flag == 'n' || flag == 'N') return 1;
}
}
}
}
}
转存钱款
int transfer(account user[], int n) //转存钱款
{
int transferid1, transferid2,transferpw;
printf("请输入需要取款的账号：");
scanf_s("%d", &transferid1);
for (int i = 0; i <= n + 1; i++)

{
for (int j = 0; j != 1;)
{
printf("请输入密码：");
scanf_s("%d", &transferpw);
if (user[i].password == transferpw)
{
printf("请输入所要转入的账户卡号:\n");
scanf_s("%d", &transferid2);
printf("请输入转入数额：\n");
float tranmoney;
scanf_s("%f", &tranmoney);
user[i].money -= tranmoney;
for (int k = 0; k <= n + 1; k++) //寻找被转入账户
{
if (user[k].id == transferid2)
{
user[k].money += tranmoney;
k = n + 2;
}
}
printf("转钱成功！，当前账户余额为：%f", user[i].money);
return 0;
}
else
{
printf("密码错误！\n");
printf("是否重输密码？Y/N\n");
char flag;
scanf_s("%c", &flag, 1);
if (flag == 'n' || flag == 'N') return 1;
}
}
}
}
}
主函数
int main()
{
int n = 1,choose;
account user[100];
user[0].id = 1000000; //初始化第一个账户
user[0].password = 0;
user[0].money = 0;
int end = 0; //是否结束，0记为不结束
do {
printf("请选择您需要进行的操作:\n1.开户\t2.销户\n3.查询当前余额\n4.存款\t5.取款\n6.转账\t0.退出\n");
scanf_s("%d", &choose);
switch (choose)

case 0:
exit(0);
case 1:
create(user, n); n++; break;
case 2:

}

case 4:

case 5:
