结构体在内存中是连续存储的
struct stu{ char *name; //姓名 int num; //学号 char sex; //性别 float score; //成绩 } stu1, stu2 = { "Tom", 10, ‘M‘, 90 }; 不过整体赋值仅限于上面这样的情况,也就是定义结构体的同时声明变量。下面的写法是错误的: stu2 = { "Tom", 10, ‘M‘, 90 };
#include <stdio.h> #define STU struct stu int main(){ STU{ char *name; //姓名 int num; //学号 char sex; //性别 float score; //成绩 }; STU stu1; stu1.name = "James Bond";//用指针指向一个字符串 stu1.num = 1; stu1.sex = ‘M‘; //用M表示男性,W表示女性 stu1.score = 99; printf("Hello everyone! My name is %s, a naughty boy, but with good scores(%.2f) and top No.(%d)!", stu1.name, stu1.score, stu1.num); return 0; }
