结构体与指针练习

#include <stdio.h>

struct people

{ char studycard[20];

  char name[20];

  int age;

};

int main()

{

struct people a = { "2022060724","张三",19 };

struct people* pb = &a;

printf("%s\n", pb->studycard);

/*printf("%s\n", (*pb).studycard);

printf("%s\n", (*pb).name);

a.age = 20;

printf("%d\n", (pb).age);效果相同*/

printf("%s\n", pb->name);

a.age = 20;

printf("%d\n", pb->age);

return 0;

}
