#include <stdio.h>

typedef struct {
    char first[20];
    char last[20];
} Name;
typedef struct {
    Name name;
    int age;
    char gender[10];
} Child;

void show(Child* pc) {
    printf("%s %s is a %d years old %s", pc->name.last, pc->name.first, pc->age, pc->gender);
}

int main(void)
{
    Child child = {
        {"Meimei", "Han"},
        10,
        "girl"
    };
    Child* pc = &child;
    printf("%d\n", child.age);
    printf("%s\n", pc->name.first);
    printf("%s\n", pc->gender);
    show(pc);
}
