用C语言模拟ATM机工作流程编程

#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环境下调郑野试雹隐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

"stdlib.h"#include

"time.h"#define

如下，实际过程中还需要加个菜单选择，另外要对用户输入进行合法性检查。

#include<stdio.h>

int main()

{

int n

char ch

printf("请输入您要取款的金额：")

scanf("%d"散行,&n)

printf("请确认您的取款金额(y 或者n):")

ch = getchar()

if(ch == 'y' &&ch =='Y') //这个是你要的算法

printf("取款%d成功\n",n)

//同样的这里可以凯州加入其它的判断，手机打字不便，自己根据盯掘蔽需要加。

return 0

}
