There are many problems with the program below. Describe 5 of these problems in detail. For each, also explain how you could fix or avoid the issue.

Program:

#include

using namespace std;

class Duck {

public:

virtual void quack() {

cout << "Quack" << endl;

}

};

class RubberDuck : public Duck {

public:

RubberDuck() {

array = NULL;

}

RubberDuck(int size) {

array = new int[size];

array[0] = 1;

array[1] = 2;

array[2] = 3;

}

~RubberDuck() {

delete array;

}

void quack() {

cout << "Squeak! ";

for (int i = 0; i < arraySize; i++) {

cout << array[0] << " ";

}

cout << endl;

}

private:

int* array;

int arraySize;

};

int main() {

Duck* rubberDuck;

Duck& duck = *rubberDuck;

duck.quack();

delete[] rubberDuck;

return 0;

}

Example Output (when all goes well):

Squeak! 1 2 3
