Thanks Rich & David.

It's just that I find the use of pointers a bit inconsistent, the syntax
and operators change depending on whether you work on discrete data
types, or complex ones like structures or arrays, so I sometimes find
myself scratching my head when I have to use pointers on my custom data
types that mix all of these 3 types... hopefully I will get the hang of
it, with practise...
