在C语言中ATM自动取款机的功能程序怎么写啊？

#include<stdio.h>

void main()

{

char SelectKey,CreditMoney,DebitMoney

while(1)

{

do{

clrscr()

puts("Please select key:")

puts("1.Quary")

puts("2.Credit")

puts("3.Debit")

puts("4.Return")

SelectKey=getch()

}while(SelectKey!='1'&&SelectKey!='2'&&SelectKey!='3'&&SelectKey!='4')

switch(SelectKey)

{

case'1':

clrscr()

puts("Your balance is $1000")

getch()

break

case'2':

do{

clrscr()

puts("Please select Credit money:")

puts("1.$50")

puts("2.$100")

puts("3.Return")

CreditMoney=getch()

}while(CreditMoney!='1'&&CreditMoney!='2'&&CreditMoney!='3')

switch(CreditMoney)

{

case'1':

clrscr()

puts("Your Credit money is $50,Thank you!")

getch()

break

case'2':

clrscr()

puts("Your Credit money is $100,Thank you!")

getch()

break

case'3':

break

}

break

case'3':

do{

clrscr()

puts("Please select Debit money:")

puts("1.$50")

puts("2.$100")

puts("3.$500")

puts("4.$1000")

puts("5.Return")

DebitMoney=getch()

}while(DebitMoney!='1'&&DebitMoney!='2'&&DebitMoney!='3'&&DebitMoney!='4'&&DebitMoney!='5')

switch(DebitMoney)

{

case'1':

clrscr()

puts("Your Debit money is $50,Thank you!")

getch()

break

case'2':

clrscr()

puts("Your Debit money is $100,Thank you!")

getch()

break

case'3':

clrscr()

puts("Your Debit money is $500,Thank you!")

getch()

break

case'4':

clrscr()

puts("Your Debit money is $1000,Thank you!")

getch()

break

case'5':

break

}

break

case'4':

return

}

}

}

几个小错误而已...比如忘了写双撇号,switch写错了...还有!= 忘了写! 等等.. 以上程序可以运行了

#include

"stdio.h"对ATM机器的模拟就是一个对队列的模拟下面代码在VC6环境下调试已经通过了其中有个缺陷就是因为代码执行速度过快导致二次执行根据时间随机出来的数字都是一样的因此你可以自己加上一个延迟子程序部分功能已经注释了#include
