谁能不翻书，不查网马上回答一下以下问题？老实说，我能完整地答上的只有OOP的第2个问题...反思中...
关于OOP
1. 解释什么是class, 什么是instance...
2. 解释什么是polymorphism...
关于Unix
1. 解释什么是shell...
2. 解释什么是unix signal...
关于数据库
1. 解释什么是key field...
2. 描述index的用途...
以上几道题是其实很有现实意义的，是某大公司developer的interview笔试题...
完整版本: 非常基础的几个CS问题
class: abstraction of a class of things
eg: class Human for all individual human beings
class Student for all the student individuals in a uni
instance(not T): a specific member of that classe
eg: gaog is an instance of a class DJTmember
Polymophism: a method can be implemented in different ways in different class
Shell: console...
unix signal: no idea
i am generally unix idiot
key field: the field used to uniquely identify a record
index: fast search
eg: class Human for all individual human beings
class Student for all the student individuals in a uni
instance(not T): a specific member of that classe
eg: gaog is an instance of a class DJTmember
Polymophism: a method can be implemented in different ways in different class
Shell: console...
unix signal: no idea
i am generally unix idiot
key field: the field used to uniquely identify a record
index: fast search

这些基础概念是最容易忽视的。

是呀，想解释好还真不容易。实事上我觉得这题目考的并不是OO概念。但凡会编程的人大概都知道class是什么。我认为这些题目考的是一个人的综合表述能力。
quite difficult...... these are not even tested in exams
