台球碰撞-题解（C语言代码）

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<math.h>

int main()

{

double L,W,x,y,R,a,v,s,vx,vy,x_zuo,x_you,y_shang,y_xia;

while(scanf("%lf %lf %lf %lf %lf %lf %lf %lf",&L,&W,&x,&y,&R,&a,&v,&s)&&L!=0)

{

     vx=cos(a*asin(1)/90)*v;

     vy=sin(a*asin(1)/90)*v;

     x=vx*s+x;

     y=vy*s+y;

     x_you=L-R;

     y_shang=W-R;

     while(x<R||x>x_you) 

     {

         if(x<R)

             x=2*R-x;

         else if(x>x_you)

             x=2*x_you-x;

     }

     while(y<R||y>y_shang) 

     {

         if(y<R)

             y=2*R-y;

         else if(y>y_shang)

             y=2*y_shang-y;

     }

     printf("%.2lf %.2lf\n",x,y);

     }

}
