c语言程序设计——抽奖程序

c语言程序设计——抽奖程序,第1张

真不好玩,写好还真不简单~

中意的话,指侍多加点分!测试过了~

/*

预先将参加抽奖者的资料输入存储起来,主要用结构体数组实现,用结构体表示每项记录,包括身份z号码、姓名、电话、住址信息。开始抽奖时,屏幕上快速闪动参与者的身份z号码,按任意键停止闪动,把中奖人的信息用显示在屏幕上。可反复抽出一、二、三等奖若干名。

设计实现以下功能:

(1)录入:完成抽奖者信息的输入;

(2)删除:完成抽奖者信息的删除;

(3)修改:允许对已经录入的数据重新进行编辑、修改;

(4)显示:显示所有中奖者的信息;

(5)抽奖:

a. 抽出一链带等奖 1 名,如果抽过就不能再抽;

b. 抽出二等奖 2 名,如果抽完就不能再抽;

c. 抽出三等奖 5 名,如果抽完就不能再抽;

(6)退出程序。*/

case 4:

case 6:

default:

break

}

}

void main()

{

while(raise())

}

代码如下,已测试通过:

int main()

{

int no,ret

printf("请输入你猜测的号码:\n")

scanf("%d",&竖芹毁no)

ret=rand()%10

printf("本次开奖结果=[%d]:\n",ret)

if(no==ret)

{

printf("恭喜你猜中了,中奖10元!\n")

}

else

{

printf("很遗憾,再来一次吧!\n")

}

return 0

}

可以把上面代码改成多次输入,即将输首乎入和取余备随机数都放在while循环中。自己修改下吧
