乒乓球C语言（c语言乒乓球比赛胜负）

本文实例为大家分享了C语言实现乒乓球比赛的具体代码，供大家参考，具体内容如下

1）、基本要求

用8个LED发光管(红黄绿)的来回滚动显示来模拟打乒乓球时乒乓球在两边球台上的来回运动。比赛双方用按钮/开关(双方各用1个按钮/开关)的方法来模拟发球与接球,即发球方按动其控制的按钮/开关/健,球从发球方一侧向对方运动(LED发光管从发球方到对方逐个点亮,滚动显示),当球运动至接球方时,接球方立即按动其控制的按钮/开关/键,“击球”使球“弹回”发球方一侧，如此周而复始，直至在规定的击球时间内有一方未能完成击球动作，从而对方得一分，然后继续比赛。比赛规则可参照一般的乒乓球比赛规则。

要求：

(1). 球以每0.5秒滚过1个LED的速度移动;

(2). 回球需在球到达后的0.5秒内进行(按下按钮),否则按失球计;

(3). 球未到达提前按下按钮按失球处理，不起回球作用;

(4). 用扩展的4个七段数码（小键盘上）为双方记分(每方2个八段码, ,按10进制计数,初始值00:00,可自行设计显示及规则)

2）、设计提示

球到达接球方后,立即读接球方的按钮状态,若未按则有效(若已按下则按失球计),然后不断读此按钮状态,直到按下代表“击球”动作。（采用中断，可以用同一个按键轮流按动识别）。

3）、进一步设计要求

(1). 在8×8点阵（虚拟大屏）同步显示球移动情况，设计显示输赢球图形状态、效果等；移动、击球等精确（中断）计时;

(2). 通过拨动开关或键盘设定改变球移动速度,即每个LED管点亮时间分别为0.5秒、0.3秒、0.2秒;通过拨动开关或键盘设定改变允许击球时间0.3秒、0.2秒、0.1秒;球移动速度取决于击球时间,即球移动速度(每个LED点亮时间)在0.2~0.5秒内可变,具体取决于球到达接球方后击球所花的时间0~0.5秒如花费的时间短则回球后球移动速度快反之回球后移动
