What is the difference between char *val and char *** val?

Question

What is the difference between char *val and char ***val. I know what pointers are but can not find anywhere what this triple star notation means.

One is a pointer to a `char`, one is an horrific mess.. :-) – Will May 19 '14 at 17:36 — Will, May 19 '14 at 17:36
_And what is char ****val and etc._:D – May 19 '14 at 17:37 — , May 19 '14 at 17:37

Each star you add is another pointer, which means that char *** val is a pointer to another pointer that points to a char pointer

The three stars/asterisks mean nothing special. Each of the stars indicate a level of indirection.

Let me exemplify:

char *val is a char pointer called val.

char **val is a pointer to a char pointer called val.

char ***val is a pointer to a pointer to a char pointer called val.

So an asterisk for each pointer level.

@bluerubez If the _reputation points are stupid_, why do you want to _upvote_? – HelloWorld123456789 May 19 '14 at 17:52
