"旋转的风车"----windows(GDI)绘图

　　　这正是秋季将尽， 冬季未到的时节。 黄土高坡上已滚起了漫天黄沙， 而这里却是万里晴空如练！  风， 丝丝入骨！ 未央柳即将枯死的枝条，仍在挣扎。 街道两旁清一色的银杏树叶， 金灿耀眼。 耀的令人感动， 感动的令人心碎！ 很显然，这又是一个悲伤的人， 和一个悲伤的故事。

　　C艹老师给我们布置了一道作业， 就是 “旋转的风车”，卧槽！ 我还几乎完全没有接触过 windows编程啊。我和室友“执手相看泪眼，竟无语凝噎！”。  无奈只有自己强势看textbook啦，然而，，，，这本书也是精炼的可以，，，，，由于是我的一位老师编写的， 我不做过多评论！ 。看着书上仅有的两个示例， 不觉我已泪流满面， 无奈， 只有强行乱写一下啦！ 心疼~~~~。
