怎樣用c語言編寫ATM系統(tǒng)
真正的ATM系統(tǒng)不可能只是用C語言編寫的，它應(yīng)該是一套完整獨立的系統(tǒng)，核心代碼更機(jī)密，不會輕易的泄露。
C語言可以寫一個類似于ATM系統(tǒng)的框架，用以模擬ATM機(jī)上的各種操作。
框架代碼如下：
#includeiostream.h??
#includestdio.h??
int?main()???
{??
int?choice?=-?1;???
while(1)?{??
printf("請選擇\n1.login\t2.regist\n");??
scanf("%d",?choice);??
switch(choice)?{??
case?1:??
login();??
break;??
case?2:??
regist();??
break;??
default:??
printf("輸入有誤，重新輸入\n");??
break;??
}??
}??
return?0;
}??
void?login()?{??
printf("IN?LOGIN\n");??
int?flag?=?-1;??
int?X?=?-1;??
printf("輸入賬戶和密碼\n");??
flag?=?search();??
if(falg?==?1)?{??
printf("存在，進(jìn)入主頁面\n");??
X?=?menu();??
if(X?==?1)??
return;??
}??
else?if(flag?==?0)?{??
printf("賬戶或密碼錯誤\n");??
return;???????
}??
}??
int?regist()?{??
printf("IN?REGIST\n");??
return?1;??
}??
int?menu()?{??
printf("IN?MENU\n");??
int?key?=?-1;??
int?N?=?-1;??
while(1)?{??
printf("請選擇業(yè)務(wù)：1.refer\t2.deposit\t3.withdraw\t4.transfer\t5.resetPW\t6.退出\n");??
scanf("%d",?key);??
switch(key)?{??
case?1:??
N?=?refer();??
break;??
case?2:??
N?=?deposit();??
break;??
case?3:??
N?=?withdraw();??
break;??
case?4:??
N?=?transfer();??
break;??
case?5:??
N?=?resetPW();??
break;??
case?6:??
N?=?6;??
return?1;??
break;??
default:??
printf("輸入有誤，重新選擇：\n");???
break;??
}??
if(N%2?==?0)?{??
printf("Error!\n");??
}???
}??
}??
int?refer()?{??
printf("IN?REFER\n");??
//輸出余額???
return?1;??
}??
int?deposit()?{??
printf("IN?DEPOSIT\n");??
//存錢???
return?3;??
}??
int?withdraw()?{??
printf("IN?WITHDRAW\n");??
//取錢???
return?5;??
}??
int?transfer()?{??
ptintf("IN?TRANSFER\n");??
//轉(zhuǎn)賬???
return?7;??
}??
int?resetPW()?{??
prtintf("IN?RESETPW\n");??
//重設(shè)密碼???
return?9;??
}
用c語言編寫ATM的程序，實現(xiàn)開戶、存款、取款、查詢余額、轉(zhuǎn)賬的業(yè)務(wù)邏輯。
