13     int left = 0;
14     int right = 20;
15     int top = 0;
16     int bottom = 10;
17 
18     while(1){
19         
20         x = x + velocity_x;
21         y = y + velocity_y;
22         system("cls");
23 
24         for (i = 0; i < x; i++)
25             cout << endl;
26         for (j = 0; j < y; j++)
27             printf(" ");
28         printf("o\\n");
29 
30         Sleep(50);
31         if (x == top || x == bottom) {
32             velocity_x *= -1;
33             printf("\\a");
34         }
35 
36         if (y == left || y == right) {
37             velocity_y *= -1;
38             printf("\\a");
39         }
40     }
41     return 0;
42 }

最基础的实现，小球撞到墙壁即反弹，触碰会发出声音，仅此而已。

时隔一年，又看到了这份代码，就发出来吧。
