步骤1：显示图片

用二维数组来显示8张90×90的配对图片，用来翻转的；首先显示的是背景图片。定义一个二维数组pic[4][4] 来表示每张小图片存放的位置，数组里面存放0～7的数字，当前位置存放是0，就表示该位置要显示image0小图片。这样就可以显示所有小图片了。

步骤2：实现可以翻转

根据鼠标点击的位置，翻转指定的小图片，而且要自动的翻转回来，主要是鼠标的获取和定位；定义一个二维数组flag[mouse_y/90][mouse_x/90] 来标志有没有翻转，鼠标点击的坐标位置除以90就可以确定点击的是哪张小图片。

步骤3：游戏逻辑翻转

所谓逻辑翻转就是根据游戏的规则翻转和不翻转图片，就是当鼠标点击次数为偶数时，判断前面的一张图片和当前这张图片是否相同，如果是相同的，这两张图片就不要翻转回背面，否则，就把这两张图片都翻转回背面。主要还是怎样判断两张图片是否相同，解决方法是根据一开始的二维数组pic[4][4]里面存放的数字是否是相同的来判断两张图片是否是相同的。直到所有的小图片都被翻转了游戏就结束。最后利用了SDL的强大功能弄了一个动画的界面来结束游戏。
