No matching function for call error with a function never called?

Matt13w (2)
I have a World class in my game that holds an array of "Regions" called _map. In the for loop to populate this array, the constructor for region takes one integer for the seed. In the header file the constructor is declared correctly as far as I can see.

        }
    }
}

I have omitted some of the other functions used in the constructors for size purposes.The error I am getting is:

D:\WorldGame\maps.cpp|243|error: no matching function for call to 'Region::Region()'|

Which is the line of code (line 243?) it's complaining about?

On line 32 of maps.h you declare World::_map, which is an array of Regions. You can't declare arrays whose elements are of a type that doesn't have a default constructor.

Oh, I didn't know I needed to do that, but now that I think about it, it makes sense I would need to do that. That fixed it, thanks much!
