本文實例講述了C++實現基于控制臺界面的吃豆子游戲。分享給大家供大家參考。具體分析如下：
程序運行界面如下所示：
ESC鍵可退出游戲。
main.cpp源文件如下：
#include "lib.h"#pragma onceextern int level;int main(){ FOOD food; WALL wall; BODY CurPos; HALL hall; int iExit = 0; while(1) { if(iExit) break; Init(&food,&wall,&CurPos,&hall); MakeWall(&wall); while(1) { Sleep(200); int res = Move(&food,&wall,&CurPos); if(1 == res) //重新開局 break; else if(-1 == res) //用戶退出 { iExit = 1; break; } ShowScore(&CurPos,&food); } } return 0;}lib.h頭文件如下：
