首次做关于游戏的小项目 一些想法和过程不是很巧妙还有待改良 仅供参考

void initMap();	//初始背背景图
void printStaticMap();	//打印静态背景图
void gotoxy();	//控制打印光标位置
void printDynamicShape();//打印动态图形
void moveDown();//向下移动
int isCrashY();	//判断是否与下面碰撞
void addStaticMap();	//将动态图形添加到静态背景图中
void moveLeft();	//向左移动
int isCrashXL();	//判断是否与左侧碰撞，能够向左移动
void moveRight();	//向右移动
int isCrashXR();	//判断是否与右侧碰撞，能够向右移动
void drawNewShape();//描绘新图形
void changeShape();//变换图形
void clearFullLine();//清除满行
int isLineFull(int line);//判断该行是否已满
void clearOneLine(int line);//清除一行
void controlSpeed();//控制速度
void printGameOver();//打印输出游戏结束提示
void isRestartGame();//是否重启游戏
