不知道什么时候开始，数学和编程被捆绑到了一起，数学不好学编程也不行，很多人的意识数学系毕业的学编程一定厉害。
只能说，确实多虑了，至于数学好就编程好更是想多了，两者也是没有绝对的关系，基本的加减乘除已经可以应付绝大多数的场景了。
这时候大家会说算法都是数学构成的啊，满满的都是数学元素。
我从大一就开始接触编程，到现在毕业两年，既在大型国企做过飞控算法，也在世界500强外企做过通信算法开发，真的没有那么多算法用你去开发，所谓的算法落实到个人就是逻辑，就是业务，你要用的算法基本都是现成的，直接用就好了，别太担心。首先说些我自己数学一般水平，高中还算喜欢，也比较擅长，但是到了大学基本就是随波逐流了，基本都是擦边过那种。
大一学习VB
这个时候学习的vb，做了个项目是一个微型的微博管理系统，主要功能就是界面可以点击登录，输入密码登录后就可以浏览图片，添加删除管理日志，还可以自定义背景图片等，时间有点久，大致功能就这些，整个项目和数学没有任何关系，是的，没有任何，这时候甚至高数都还没学完，主要的难度都是逻辑上，要设计什么功能等，VB的编程也是模块式开发，基本的控件都是现成的，只需要添加想要的逻辑就可以。
举个当时写的判断闰年的例子
Private Sub Form_Click() Dim y% y = InputBox("y=")If y Mod 400 = 0 Then Print "是闰年" Else If y Mod 100 = 0 Then Print "不是闰年" Else If y Mod 4 <> 0 Then Print "不是闰年" Else Print "是闰年" End If End IfEnd IfEnd Sub 同理，学习C语言
C语言相较于VB确实难度提升了很多，但是基本的功能实现也只是加减乘除罢了，我大学之后几年一直是在做嵌入式相关，主要涉及的语言就是C语言，代码行数确实很多，但是和数学关系不大。
大部分的代码都是逻辑代码，也就是if else,这也就是为什么说if else 就完成了基本的代码，至于算法绝大多数都被封装好了，直接调用就好。下边给大家看一个摇摇棒的项目，看着还挺复杂，实际分析下还是基础的逻辑构成。一直想强调的就是逻辑很重要，别自己吓自己，真不是数学的锅。
