c++ - Pointer question -

i have class example:

class local {    public:     int var; };   local * plocal = (local *)0x74673; local * plocal2 = *(local **)0x74673; 

i know means nothing it's example...

i want understand diff between plocal , plocal2

plocal2 pointer local structure, pointer taken address 0x74673.

plocal pointer local structure, structure allocated @ memory address 0x74673
