PS:今天上午,非常郁闷,有很多简单基础的问题搞得我有些迷茫,哎,代码几天不写就忘。目前又不当COO,还是得用心记代码哦!

    每日一道理
翻开早已发黄的页张,试着寻找过去所留下的点点滴滴的足迹。多年前的好友似乎现在看来已变得陌生,匆忙之间,让这维持了多年的友谊变淡,找不出什么亲切感,只是偶尔遇上,淡淡地微笑,如今也只能在这发黄的页张中找寻过去的那些让人难忘的,至少我可以握住这仅剩下一段的“丝线头”……

文章结束给大家分享下程序员的一些笑话语录: 面试官:熟悉哪种语言
应聘者:JAVA
面试官:知道什么叫类么
应聘者:我这人实在,工作努力,不知道什么叫累
面试官:知道什么是包?
应聘者:我这人实在 平常不带包 也不用公司准备了
面试官:知道什么是接口吗?
应聘者:我这个人工作认真。从来不找借口偷懒
面试官:知道什么是继承么
应聘者:我是孤儿没什么可以继承的
面试官:知道什么叫对象么?
应聘者:知道,不过我工作努力,上进心强,暂时还没有打算找对象。
面试官:知道多态么?
应聘者:知道,我很保守的。我认为让心爱的女人为了自已一时的快乐去堕胎是不道德的行为!请问这和C#有什么关系??
