#define后面的又是#号，又是（） __什么的，到哪里可以学到啊，什么书上有，我也想学学写那变态的玩意

[解决办法]
#可以将后面的内容转换成字符串，如#*可以将* 转换成“*”
##是连接符如“Hello ”##“World”==“Hello World”
可以参看C/C++*精粹（人民邮电的一本书，名字记不太全）
还有《C语言参考大全》

[解决办法]
[推]《C语言的科学和艺术》，斯坦福的教授所著，公认的优秀教材。
书中教学用的库（http://download.csdn.net/user/RoderickA），
Dev C++（http://www.skycn.com/soft/4639.html）.

注：前面用英文注释的（用//的部分）。
总的来说，就是在预编译时该怎么处理。呵呵
