Pointer to Array of Structs

Got a quick question for everyone. Let's say that I have an array of pointers that points to an array of structs. Such as:

HashNode ** Htable; //where HashNode is a struct
HashNode * pa;
pa=Htable;

Now, to access the second element in this array of HashNodes can I just increment pa using the ++ operator or do I need to use the sizeof(HashNode) to increment this to the next element in the array?

Thanks for the Help.

just use ++ as in

pa++;

the size of each element is automatically taken into account(that is if your not doing crazy stuff you probably shouldnt be).

Are you aware that you can also say pa[x][y]...
