嵌套结构的内存布局

c
#include

    char city[20];
    char state[20];
};

    char name[50];
    int age;
    struct Address address;

int main() {
    struct Person person;
    
    printf("Enter name: ");
    scanf("%s", person.name);
    
    printf("Enter age: ");
    scanf("%d", &person.age);
    
    printf("Enter city: ");
