這篇文章主要為大家詳細(xì)介紹了C語(yǔ)言實(shí)現(xiàn)乒乓球比賽，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了C語(yǔ)言實(shí)現(xiàn)乒乓球比賽的具體代碼，供大家參考，具體內(nèi)容如下

1）、基本要求

用8個(gè)LED發(fā)光管(紅黃綠)的來(lái)回滾動(dòng)顯示來(lái)模擬打乒乓球時(shí)乒乓球在兩邊球臺(tái)上的來(lái)回運(yùn)動(dòng)。比賽雙方用按鈕/開(kāi)關(guān)(雙方各用1個(gè)按鈕/開(kāi)關(guān))的方法來(lái)模擬發(fā)球與接球,即發(fā)球方按動(dòng)其控制的按鈕/開(kāi)關(guān)/健,球從發(fā)球方一側(cè)向?qū)Ψ竭\(yùn)動(dòng)(LED發(fā)光管從發(fā)球方到對(duì)方逐個(gè)點(diǎn)亮,滾動(dòng)顯示),當(dāng)球運(yùn)動(dòng)至接球方時(shí),接球方立即按動(dòng)其控制的按鈕/開(kāi)關(guān)/鍵,“擊球”使球“彈回”發(fā)球方一側(cè)，如此周而復(fù)始，直至在規(guī)定的擊球時(shí)間內(nèi)有一方未能完成擊球動(dòng)作，從而對(duì)方得一分，然后繼續(xù)比賽。比賽規(guī)則可參照一般的乒乓球比賽規(guī)則。

要求：

(1). 球以每0.5秒滾過(guò)1個(gè)LED的速度移動(dòng);

(2). 回球需在球到達(dá)后的0.5秒內(nèi)進(jìn)行(按下按鈕),否則按失球計(jì);

(3). 球未到達(dá)提前按下按鈕按失球處理，不起回球作用;

(4). 用擴(kuò)展的4個(gè)七段數(shù)碼（小鍵盤(pán)上）為雙方記分(每方2個(gè)八段碼, ,按10進(jìn)制計(jì)數(shù),初始值00:00,可自行設(shè)計(jì)顯示及規(guī)則)

2）、設(shè)計(jì)提示

球到達(dá)接球方后,立即讀接球方的按鈕狀態(tài),若未按則有效(若已按下則按失球計(jì)),然后不斷讀此按鈕狀態(tài),直到按下代表“擊球”動(dòng)作。（采用中斷，可以用同一個(gè)按鍵輪流按動(dòng)識(shí)別）。

3）、進(jìn)一步設(shè)計(jì)要求

(1). 在8×8點(diǎn)陣（虛擬大屏）同步顯示球移動(dòng)情況，設(shè)計(jì)顯示輸贏(yíng)球圖形狀態(tài)、效果等；移動(dòng)、擊球等精確（中斷）計(jì)時(shí);

(2). 通過(guò)撥動(dòng)開(kāi)關(guān)或鍵盤(pán)設(shè)定改變球移動(dòng)速度,即每個(gè)LED管點(diǎn)亮?xí)r間分別為0.5秒、0.3秒、0.2秒;通過(guò)撥動(dòng)開(kāi)關(guān)或鍵盤(pán)設(shè)定改變?cè)试S擊球時(shí)間0.3秒、0.2秒、0.1秒;球移動(dòng)速度取決于擊球時(shí)間,即球移動(dòng)速度(每個(gè)LED點(diǎn)亮?xí)r間)在0.2~0.5秒內(nèi)可變,具體取決于球到達(dá)接球方后擊球所花的時(shí)間0~0.5秒如花費(fèi)的時(shí)間短則回球后球移動(dòng)速度快反之回球后移動(dòng)
