Thread: Pointers to multi dimensional arrays.

Hi I was creating a class to initalize a series of blocks like in a break out game. I created a pointer as a private member and then used this code to initalize it.

Code:

blockPointer = new Block[3][6];

Then Visual C++ started generating errors like. Can't convert Block * to Block * [3]....

I thought you could create pointer to arrays like that. Is there something I am neglecting??

Is there something I am neglecting??
blockPointer = new Block[3][6];

Yeah, the type on the left has to match the type on the right. The leftmost dimension isn't part of the type of an array, so the type on the right is:

Block[][6]

Since new returns an address of dynamically allocated memory for that type, you have to make sure your variable blockPointer was declared as a pointer to that type. The syntax for that is:

Block (*blockPointer)[6];

Thanks mate I will remember that I just decided in the end it would be easier instead of creating a multi array of [3][6]. To jsut create a single one of [18]. Otherwise I would have to edit all my class files and considering it was a simple example I didnt want to have to do that.
Thanks agen
