贺老师教学链接C语言及程序设计进阶本课讲解
结构体作函数参数
#include <stdio.h>struct Student{int num;char name[20];char sex;int age;double score;char addr[30];};void print(struct Student s){printf("%d %s %c\n", s.num, s.name, s.sex);//可再加……return;}int main(){struct Student student1,student2;struct Student *p_stu;student1.num=10001;student2.age=120;p_stu=&student2;print(student1);print(*p_stu);return 0;}
当结构体成员又是结构体……
#include <stdio.h>struct Date{int month;int day;int year;};struct Student{int num;char name[20];char sex;struct Date birthday;float score;} student1,student2= {10002,"Wang Li",'f',5,23,1982,89.5};int main( ){student1=student2;printf("%d\n", student1.num);printf("%s\n", student1.name);printf("%c\n", student1.sex);printf("%d/%d/%d\n", student1.birthday.month, student1.birthday.day, student1.birthday.year);printf("%.1f\n", student1.score);return 0;}
结构体的成员是数组
#include <stdio.h>#include <string.h>struct Student{int num;char name[10];double score[3];};void print(struct Student);int main( ){struct Student stu;stu.num=12345;strcpy(stu.name, "Li Fung");stu.score[0]=67.5;stu.score[1]=89;stu.score[2]=78.5;print(stu);printf("%d %s ", stu.num, stu.name);printf("%.1f %.1f %.1f\n", stu.score[0], stu.score[1], stu.score[2]);return 0;}
void print(struct Student s)
{
printf("%d %s ", s.num, s.name);
printf("%.1f %.1f %.1f\n", s.score[0], s.score[1], s.score[2]);
}
