c语言：通过指向结构体变量的指针变量输出结构体变量中成员的信息

通过指向结构体变量的指针变量输出结构体变量中成员的信息。

解：程序：

#include<stdio.h>

#include<string.h>

int main()

{

struct Student

{

long int num;

char name[20];

char sex[10];

float score;

};

struct Student stu_1;//定义struct Student类型的变量stu_1

struct Student *p;

p = &stu_1;

stu_1.num = 1010;

strcpy(stu_1.name, "Li Lin");//用字符串复制给stu_1.name赋值

strcpy(stu_1.sex, "Man");

stu_1.score = 89.5;

printf("num:%ld\nname:%s\nsex:%s\nscore:%5.1f\n", stu_1.num, stu_1.name, stu_1.sex, stu_1.score);

printf("\nnum:%ld\nname:%s\nsex:%s\nscore:%5.1f\n", (*p).num, (*p).name, (*p).sex, (*p).score);

return 0;

} 

结果：

num:1010

name:Li Lin

sex:Man

score: 89.5

 

num:1010

name:Li Lin

sex:Man

score: 89.5

请按任意键继续. . .
