函数函数入门为什么需要函数？
请完成这样一个需求：输入两个数，再输入一个运算符加减乘除，得到结果。
先使用传统方式来解决，看看有什么问题没有：
代码冗余（过多重复代码）
不利于代码的维护
复用性困难

C语言C语言的特点及入门代码级别的跨平台：由于标准的存在，使得几乎同样的C代码可用于多种操作系统，如Windows,Dos,Unix等等，也适用于多种机型。
由于C语言允许直接访问物理地址，可以直接对硬件进行操作，因此它即具有高级语言的功能，又具有低级语言的许多功能，C语言可以用来写系统软件（比如操作系统，数据库，杀毒软件，防火墙，驱动，服务器）
C语言是一个有结构化的程序设计，具有变量作用域(variable scope)以及递归功能的过程式语言
C语言传递参数可以是值传递(pass by value)传递的是值,也可以传递指针(a pointer passed by value)传递的是地址。
C语言中，没有对象，不同的变量类型可以用结构体(struct)组合在一起，不是面向对象的。
预编译处理(preprocessor),生成目标代码质量高，程序执行效率高
为什么主函数定义为int型 在C99标准未发布前，一般把main函数定义为void，即无返回值类型，c99标准发布后，里面明确规定定义main时要定义成int型，原因是因为main函数是系统调用的，在main函数运行结束后，要 ...
