struct Person {
    int age;
    char name[50];
    void (*greet)(void);
};

void Person_greet(struct Person *person) {
    printf("Hello, my name is %s and I am %d years old.\n", person->name, person->age);
}

int main() {
    struct Person person;
    person.age = 30;
    person.name[0] = 'J';
    person.name[1] = 'o';
    person.name[2] = 'n';
    person.name[3] = 'e';
    person.name[4] = '\0';
    person.greet = Person_greet;
    printf("Hello, my name is %s and I am %d years old.\n", person.name, person.age);
    return 0;
}
