一、作用：对源程序编译之前做一些处理,生成扩展C源程序 二、种类 三、宏定义 #define

#include #include struct snode char name[ 15 truct snode*next struct snode *create list(int n)

#include struct Worker Int num char name[20] maino float sum=0 truct Worker*p, per[3]: printf(\请输入三名职工的编号、姓名、性别和工资:in\)

#include struct Student float score struct Student sa={\李飞\,100},sb={\于凡\,72.5}; struct Student*p,[3}{\宋石\,93.5} s[lFsa; *结构体变量(整体)赋值*

#include struct student Int num Int age; float score
