包含基类/派生类对象的c++数组

我正试着把一个任务放在一起，却卡在了一点上。问题是用Student派生类创建Person类。然后重载<<和>>运算符。最后，创建检查程序来创建包含20个人的数组，并继续加载Person或Student。在任何时候，我们都可以打印到目前为止的结果——Person输出是Name char*/Age int/Parents *char[2], Student输出是Name char*/Age int/ID int。

我的问题是与数组点-我不知道如何实现这一点，现在我被困在:

• 指向person的指针数组
• 如果是人/学生我们选择
• istream获取数据

下面是主要代码部分:

#include <iostream>
#include <conio.h>
#include "Header.h"
using namespace std;
int main()
{
    char choice;
    Person* Tablica[20];
    Person* temp;
    int i = 0;
    while (1)
    {
        cout << "choices:" << endl;
        cout << "(p)erson, (s)tudent, s(h)ow, (e)nd" << endl;
        choice = _getch();
        if (choice == 'h' || choice == 'H'){
            for (int n = 0; n < i; n++){
                cout << *Tablica[n] << endl;
            }
        }
        if (choice == 'e' || choice == 'E'){ break; }
        if (choice == 'p' || choice == 'P'){
            temp = new Person;
            cin >> *temp;
            Tablica[i] = temp;
            cout << *Tablica[i] << endl;
            i++;
        }
        if (choice == 'S' || choice == 's'){
            temp = new Student;
            cin >> *temp;
            Tablica[i] = temp;
            cout << *Tablica[i] << endl;
            i++;
        }
    }
    system("PAUSE");
    return 0;
}

我能够加载第一个人/学生，然后代码中断没有错误。所以我想问的是，你能看一下代码给我指出正确的方向吗?

免责声明:我们必须使用数组，不能使用向量等。是的，conio.h也在那里，它必须留在那里……显然我是初学者。
