c语言 程序引用结构体,C语言及程序设计进阶例程

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

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

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

#include

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]);

}
