#include <stdio.h>

#include <string.h>

struct Person

{

char name[20];

int age;

char address[100];

};

void setPerson(struct Person *p)

{

strcpy(p->name, "백지헌");

p->age = 20;

strcpy(p->address, "서울시");

}

int main()

{

struct Person p1;

strcpy(p1.name, "장원영");

p1.age = 19;

strcpy(p1.address, "부산시");

setPerson(&p1);

printf("%s\n", p1.name);

printf("%d\n", p1.age);

printf("%s\n", p1.address);

return 0;

}
