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
