ATM简易模拟（C语言）

简易的实现了ATM的工作流程

代码逻辑并不多，主要是对循环的使用，而且做的比较简易，任然有些bug未去解决

代码如下：

int main()
{
    int choice = 0;
    int password = 123;
    int scanpwd = 0;
    int money = 1000000;
    int chance = 3;
    int Imoney = 0;
    printf("*******************\n");
    printf("欢迎光临\n");
    printf("*******************\n请输入密码：");
    while (1){  
    scanf("%d",&scanpwd);
    if (scanpwd == password) {
        break;
    }else{  
        chance--;
        if (chance > 0){
        printf("*******************\n");
        printf("输入密码错误，请重新输入，您还有%d次机会\n",chance);
        printf("*******************\n");
        printf("请重新输入密码:");
        }else{
          printf("*******************\n");
          printf("输入错误次数达到上限，账号也被冻结，请到柜台解锁\n");
          exit(EXIT_FAILURE);
        }
      }
    }
    while (1){
      printf("*******************\n");
      printf("1.取款\n");
      printf("2.存款\n");
      printf("3.更改密码\n");
      printf("4.退出\n");
      printf("*******************\n");
      printf("请选择功能：");
      while (1){
          scanf("%d",&choice);
          if (choice > 0&&choice < 5){
              break;
          }
          else {
              printf("请输入正确的序号：");
          }
      }
      switch (choice){
      case 1:
          printf("请输入取款金额：");
          scanf("%d",&Imoney);
          money = money - Imoney;
          while (1){
              if (money > 0) {
                  printf("取款成功，余额：%d\n", money);
                  break;
              }else{
                  printf("余额不足\n");
                  break;
              }
          }
          break;
      case 2:
          printf("请输入存款金额：");
          scanf("%d",&scanpwd);
          money = money + scanpwd;
          printf("存款成功，余额为：%d\n",money);
          break;
      case 3:
          printf("请输入原密码：");
          scanf("%d",&scanpwd);
          if (scanpwd == password){
              printf("请输入新密码：");
              scanf("%d", &scanpwd);
              password = scanpwd;
              printf("请确认新密码：");
              scanf("%d", &scanpwd);
              if (scanpwd == password){
                  printf("密码更改成功！！！\n");
                  password = scanpwd;
              }else{
                  printf("两次密码不一致，请重新设置密码\n");
              }
          }else{
              printf("密码错误！！！\n");
          }
          break;
      case 4:
          exit(EXIT_SUCCESS);
      default:
          break;
      }
    }
    return 0;
}

以上的代码能够简易的实现ATM机的工作流程，嗯，，，重点是简易
