今天头天编VC++,先出了个破毛病说：“libcmtd.lib(crt0.obj) : error LNK2001: unresolved external symbol _main”

还好网上有个高手写了个文章，我已经收录到《高手们的杰作》里了，可是解决了这个问题，又出了个更奇怪的毛病，

077d213da"指令引用的"0xcccccccc"内存。该内存不能为"read

这不跟我扯呢吗，人家这个错误更经典，都不写到编译器的输出栏里，输出栏写的没错误，这毛病人家单弹出来一个窗口，网上查了一个文章，也没解决。网上说是线程的问题，可是根据网上的说法对vc++6.0作了改动，结果还是一样。

先把自己写得代码发上来吧！哪位高手愿意来帮帮忙，感激不尽！

谢谢了
