MIT Introduction to Computer Science and Programming (Lesson one )


这篇文是记载 MIT 计算机科学及编程导论 第一集 的笔记

Lesson one : Goals of the course;what is computation;introduction to data types,operators,and variables

一 讲解课程的任务、课程目标

目标

  • 像一个计算机科学家一样思考
  • 都能够读写程序
  • tacking technical problems

技巧

  • 学会写小规模的程序,来培养自己的计算思维
  • 学习读别人代码,并且应用来写出自己风格的代码
  • 了解计算机的基础以及局限

二 There is no best language

  • they all are description diferent things, having said that , some of them are bettr suited for something than others.
  • Matlab is great for doing things with vactors and mathices.
  • C is better to control date networks (术业有专攻,每个不同的语言都有它的用武之地)
  • high level VS low level Language
  • General VS targeted Language
  • compiled VS interpreted Language
  • python is High , general-purpose, interpreted language

三 statics , string ,numbers , some others etc…

  • 代码风格可以使我们避开简单的语义错误
  • 一些简单的代码
