奥 git _a

它用于我的 C 编程类(class)，它是一个简单的 ATM，可以执行 4 个操作:提款，存款，帐户详细信息，检查用户余额，然后退出。我已经做了简单的基础，但由于项目要求的变化，我现在需要在其中放置密码因素，我已经尝试过并提出了使用以下代码，但我想让它在主菜单之前要求输入密码，即:存款、取款等...我也尝试过使用 switch case 但我觉得这没有改变任何东西。任何帮助都是非常感谢。

到目前为止我完成的代码是:

 #include<stdio.h>
 #include<conio.h>
  int atmfun();
 main()
 {
 int option1;
 do
 option1=atmfun();
  while (option1==1);

  getch();
  }

  int atmfun()
  {


  char Name1[]="Fever";
  char Name2[]="JACK";
  char Name3[]="JOHN";
  char choice='y',choice1='n';
  char FullName1[]="Fever tyrell";
  char FullName2[]="Jack williams";
  char FullName3[]="John Mason";
  int i,a,AccBalance = 20000;
  int acc_type,password,option,option1;
  int passworda=31081;
  int passwordb=12345;
  int passwordc=12456;
  int w_amount,d_amount;
  printf("Welcome to generic ATM\n");
  printf("\n\nPlease choose an option...");
  printf("\n(1)View account details.");
  printf("\n(2)Check balance.");
  printf("\n(3)Withdraw amount.");
  printf("\n(4)Deposit amount.");
  printf("\n(5)Exit.\n");
  scanf("\n%d",&option);



                //start of option 1
                if(option==1) //if user wants to view their account details
                {
                    printf("PLEASE ENTER YOUR PASSWORD:  ");
                    scanf("%d",&password);          

                if 
            (password!=passworda&&password!=passwordb&&password!=passwordc)

                    printf("YOU HAVE ENTERED AN INVALID PASSWORD");
                else
                if(password==passworda)
                {
                    printf("WELCOME Mr.%s\n\n",Name1);

int main(){
  while true{
    if (checkPassword()) handleTransaction();
  };
};

看看如果你不做 main 中的所有事情是多么容易吗？
