大部分同學(xué)學(xué)習(xí)C語(yǔ)言編程以后不知道能通過(guò)什么樣的項(xiàng)目才可以鍛煉自己的思維功力，2048相信大家都應(yīng)該熟悉，不管是手機(jī)上還是網(wǎng)頁(yè)版的相信大家都玩過(guò),這個(gè)簡(jiǎn)單的控制臺(tái)版本的游戲是我曾經(jīng)在偉易達(dá)上班時(shí)一個(gè)嵌入式應(yīng)用游戲部門(mén)的大佬設(shè)計(jì)的，適合于喜歡用C語(yǔ)言寫(xiě)一些簡(jiǎn)易的游戲的朋友,邏輯性很強(qiáng)。
一、2048游戲原理
在最初的游戲, 它始于一個(gè)空4 x 4游戲板。
1)在空位置的游戲板上，每一輪游戲產(chǎn)生一個(gè)“2”或“4”隨機(jī)的數(shù)字。
2)接下來(lái),玩家輸入的上移，下移，左移或右移命令移動(dòng)塊。兩個(gè)相鄰塊相同的號(hào)碼,若是Q,可以組合成一個(gè)塊數(shù)量2Q。
3)如果沒(méi)有空間產(chǎn)生一個(gè)新的數(shù)字塊,玩家則game over。
4)想贏得游戲,玩家需要產(chǎn)生一塊2048數(shù)字塊。
二、2048游戲文檔
當(dāng)然，這些游戲的邏輯不是大家悶著腦子就能空想出來(lái)的，它一定有很規(guī)范的說(shuō)明文檔，由專業(yè)的人來(lái)書(shū)寫(xiě)，最后軟件工程師參考對(duì)應(yīng)的文檔編寫(xiě)自己的代碼

}四、運(yùn)行結(jié)果
游戲主菜單界面，通過(guò)方向鍵選擇，分別有NORMAL(正常進(jìn)行游戲)、DEBUG(調(diào)試模式)、EXIT(退出游戲)
按回車(chē)鍵進(jìn)入對(duì)應(yīng)的模式。
用字母a、d、w、s、q分別代替左右上下以及退出鍵。
如果最后游戲成功了，則會(huì)提示成功，如果失敗則會(huì)退出程序。
詳細(xì)的游戲邏輯可通過(guò)代碼以及文檔進(jìn)行了解。
