Question

In code:

struct tagPaint
{
}Paint,//<<<--------------what's this (Paint)?
*pPaint;//<<<-------------and this(*pPaint)?

I mean do I declare variable with name Paint of type tagPaint and pointer called pPaint to tagPaint?
Thanks.

Paint is a variable of type tagPaint. pPaint is a pointer to type tagPaint. If you want them to define types, then you need:

typedef struct tagPaint {
   ...
}  Paint, * pPaint;

but this is C usage – you should not be writing code like that in C++. and even in C, defining a type that hides the fact that something is a pointer is considered bad style.
