How to create an array of pointers to object of a inherit class

[ptrpham1234]

Consider the following code

class Shape
{
protected:
    int length, height;
public:
    Shape();
    ~Shape();
};

class Square : Shape
{
private:
    double Area;

public:
    Square();
    ~Square();
};

class Circle : Shape
{
private:
    double Circumference;

public:
    Circle();
    ~Circle();
};

int main() 
{

    Shape *shape[5];
    int choice, i = 0;

    cout << "Which shape are you making?\n";
    cout << "1. Square\n";
    cout << "2. Circle\n";
    cin >> choice;

    if (choice == 1)
    {
        shape[i] = new Square();
        i++;
    }

    if (choice == 2)
    {
        shape[i] = new Circle();
        i++;
    }
    

}

How would I make an array of pointers that contain both Circle and Squares so I can easily access both later to do stuff with it.

Remove lines 15 and 21.
Put lines 7 to 22 within a loop that iterates 5 times

for (int i = 0; i < 5; i++)
{
    // Square/Circle choice code + shape[i] assignment
}

And change line 18 to else if.
