c语言接小球游戏

⑴ c语言实现用小球消除砖块，鼠标控制挡板，求源代码

}
}
}
}
void gameover()//游戏结束
{
EndBatchDraw();
closegraph();

⑵ 用c语言编写一个程序模拟小球的自由落体运动

原题：一球从100m高度自由落下，每次落地后反弹回原来高度的一半，在落下。求它在第10次落地时，共进过多少m?第10次反弹的高度是？
源代码：
main()
{float sn=100,hn=sn/2; 我觉得此处的hn恒等于sn\2,正确的写法应该把此句写到
int n; for循环里。
for (n=2;n<=10;n++)
{sn=sn+2*hn;
hn=hn/2;
}
printf("第10次落地时共经过%f米.\n",sn);
printf("第10次反弹%f米.\n",hn)
}

自己改参数

⑶ 求一个C语言小球自由落体的代码，要求超过100行

#include<stdio.h>

intmain(){
	intcurve[31][37]={0};//图像保存在30*36矩阵内
	doubleA,AM=30;//第一周期幅值
	doublek=0.18;//幅值递减率
	inti,x,y;
	for(i=0;i<4;++i){//共画出4个周期
		A=(1-i*k)*AM;
		for(x=0;x<9;++x){//每个周期用9个点描画
			y=-(int)(x*A*(x-8)/16.0);
			curve[y][x+i*8]=1;
		}
	}
	for(y=30;y>=0;--y){
		for(x=0;x<37;++x){
			if(curve[y][x])printf("+");
			elseprintf(".");
		}
		printf("
");
	}
	return0;
}
