How to call the constructor in this case

Hi there!
I´m in doubt(of course)! How can I call the constructor of objects that are in an array within a constructor of another class ?
Note: the array isn´t of pointers!
I´m sending my two files for better explanation
Thanks for any help!:p

Note: I´m getting this erros when trying to compile:
no matching function for call to `Piece::Piece ()'

If you have an array of objects that need constructing, then that object must have a default constructor. If a default constructor doesn't work in your case - then use an array of pointers and allocate each element.

I didn't look at your code, but I think I have a pretty good idea of what you're asking.

I don't think this is true, consider the following:

Code:

---

class Piece
{
public:
    Piece(int id) : m_id(id) {};
    ~Piece() {};

protected:
    int m_id;
};

...

Piece Pieces[5] = { Piece(0), Piece(1), Piece(2), Piece(3), Piece(4) };

First: thanks!
Second: I thought about using pointers, but it would be a extreme wast of time for me, since I would have to deallocate and reallocate objects all the time, or change pointers... I prefer to switch among the types of pieces... is not possible that this can´t be done! :(

But I have a 8x8 matrix! This means calling the constructor 64 times!

I come back to the boards and get schooled by Eibro - with a cool new avatar too! :)

gustavosserra, it is possible, use static initialization like Eibro showed.

Yep, its gotta happen somehow. Either the compiler will generate the code for you (if you have a default constructor) or you will have to do it yourself with static initialization or a for loop and pointers.

*sigh* this is so sad :(
But thanks you all! I will use pointers...

can't you use a vector or something?
