tc下编译无错，但生成可执行文件有错，望高手指点

你要干什么？说明白
----------------解决方案--------------------------------------------------------
是在求什么方程组吗~？

什么啊

叫人怎么看？
----------------解决方案--------------------------------------------------------
是不是吃饱没事做呀！
也用不着玩这种吧！
----------------解决方案--------------------------------------------------------
太厉害了吧那是什么？？？？？？？？？？
