can anybody give me an example on a double pointer array?

lets say I have **array[x][y];
where x and y are other pointers *x and *y.
if that's possible. I want to know how I would use a double pointer array to access the values in it or to pass them to another variable or array. The thing with the double pointers is really confusing in C.

What are you actually trying to do? **array[x][y] is an array with two dimensions, of pointers to pointers.

I'm just trying to understand how **array works. Can you give me an example on how you would use **array to access the data in the array, or input data into the array?

Do you know how an array works?
... No: Arrays in C - Cprogramming.com

Do you know how a pointer works?
... No: Pointers in C - Tutorial - Cprogramming.com

Do you know how a pointer to a pointer works?
... No: Go back and read this again.

If you know all of the above, then you should have your answer. If not, get reading.

You need first to intialize your array (the xMax dimension). Then you need to initialize every row (the yMax dimension). After you done that you can use it like a normal array. Also, you may find useful to deallocate your array when you no longer need it.
