关于C++指针与结构体的使用问题及代码咨询

我最近一直在琢磨指针和结构体怎么配合使用，特意写了段代码来练手：

#include <iostream>
using namespace std;
struct Person {
    char name[20]; // *Question 2*
    int id;
};
const int max_num_of_childs=10;
struct Family {
    Person dad;
    Person mom;
    int num_of_childs;
    Person* child[max_num_of_childs];
};
void add_child (Family& f) {
    char answer;
    do {
        if (f.num_of_childs==max_num_of_childs) {
            cout << "no more children" <<endl;
            return;
        }
        cout << "more ...";
