easyx和c++制作反弹球消方块的要求

反弹球游戏和消方块游戏都是比较经典的小游戏，使用easyx库可以很方便地实现这两个游戏。下面是反弹球游戏和消方块游戏的要求：

反弹球游戏要求：
1. 画出一个小球和一个挡板；
2. 小球从挡板上方开始运动，碰到边界会反弹；
3. 小球碰到挡板会反弹，如果小球落到挡板下方，则游戏结束；
4. 挡板可以左右移动，通过键盘控制；
5. 当小球碰到砖块时，砖块会消失，小球会反弹；
6. 当所有砖块都被消除时，游戏胜利。

消方块游戏要求：
1. 画出一个矩形区域，里面有多个小矩形组成的砖块；
2. 有一个小球从上方开始运动，碰到边界会反弹；
3. 有一个挡板可以左右移动，通过键盘控制；
4. 当小球碰到砖块时，砖块会消失，小球会反弹；
5. 当所有砖块都被消除时，游戏胜利；
6. 如果小球落到挡板下方，则游戏结束。
