科技公司薪金揭秘：谷歌人均年薪15万美元 本文发表于 2009-05-29 10:27 | 5458次阅读 | 来源：腾讯科技 | 共有评论(12)条发表评论 近日，百度员工罢工告一段落。据说，这一轰轰烈烈的罢工与百度雇员不满公司月初大幅削减销售人员的底薪并同时上调公司销售目标有关。 有意思的是，根据我读到的一个科技博客，百度去年平均每员工为公司创造利润达163，844美金，排名全球众多科技公司这一指标下的NO.3，仅次于Google和微软

原创转载：C++调用方式总结

__stdcall: _stdcall 调用约定相当于16位动态库中经常使用的PASCAL调用约定。在32位的VC++5.0中PASCAL调用约定不再被支持（实际上它已被定义为__stdcall。除了__pascal外，__fortran和__syscall也不被支持），取而代之的是__stdcall调用约定。两者实质上是一致的，即函数的参数自右向左通过栈传递，被调用的函数在返回前清理传送参数的内存栈，但不同的是函数名的修饰部分（关于函数名的修饰部分在后面将详细说明）。<

先啰嗦一下，链表的题有一个特点，一旦你把解题思路理清之后，第一件事就是数一下变量的个数，一定要数清楚。链表的解题逻辑确定之后变量个数也是确定的，只能多用不能少用，少用一个就会导致程序特别复杂甚至写不出来，所以面试的过程中千万不要为了节省一个变量而折腾。
