double pointer array

How to initialize double pointer array..?

  int (**aLines)[2];
You can start by not calling it a "double pointer", it adds nothing to understanding what it is.

What do you want to initialise it with?
Array of pointers to pointer..
1). int (**aLines)[2] = 0;
2). int (**aLines)[2] = NULL;
3). int (**aLines)[2] = nullptr;
4). int (**aLines)[2] = {};
5). int (**aLines)[2] {};
