Thread: dynamic array

Assume that Disk and Tower are both classes. Furthermore assume the following header and constructor for class Triad:

Code:

class Triad
{
	friend std::ostream& operator <<(std::ostream& lhs, Triad& rhs);

public:
	Triad(int diskCount = 3);
	~Triad();

	void run();
	void run(Tower* source, Tower* waypoint, Tower* dest, int toMove);

private:
	Tower hanoi[3];
	Disk* disks;
	int diskNo;

	void sort_disks(); // sorts disks from greatest to least
};

Triad::Triad(int diskCount)
:diskNo(diskCount)
{
	disks = new Disk[diskNo];
	sort_disks();
}

I have already included <iostream>, <string>, and <iomanip>, though I'm not so sure that's making any difference here.

What I want to ask is when that constructor is called with diskCount being 2 or higher, why in the world would disks not get more than one element?

Thank you in advance.

It would always get more than one element. Why do you think it doesn't?

BTW, there's really no reason to use a dynamic array here unless you have to for learning purposes. A vector is a much better solution in C++.

It doesn't get more than one element. I kept on having the thing crash on me, so i went through the code with the debugger. As I was checking the debugger, I learned that it did not get more than one element.

Nevermind about what I said. Apparently the debugger isn't very good about showing the contents of dynamic arrays, and its serious readability problems on that issue misled me. Thanks Daved.
