Ah!, Finally thank you very much!.
Was looking all over for this.

I actually tried it before I found this, just didn’t think of the need for the reverse deallocation.

It is kinda weird that, my beginners book(Which i am done with!), GameDev, and some other C++ sites, which include beginner guides did not include this(Or they just made it really hard to find)

Well thank you again, now i can continue.

or do it in one shot instead:

// the parens are necessary
char (*p2d)[COLUMNS] = new char[ROWS][COLUMNS];

p2d[1][1] = ‘x’;

delete [] p2d; // don’t forget the []

you can easily see that constructors and destructors are properly called by allocating an array of a simple class that writes output from them.

Nice article about multidimensional arrays! I was looking for something like this. Your example is very clear and avoids confusing by using a simple delete [] array[i] instead of pointer notation.
