'pointer' is the same as 'address'.

Man, you definetely need to read books. What do you want to compare ?
Strings or pointers or pointers to pointers ?
(s1==s2) ==> !strcmp(s1,s2) [ this is one string ]
(&s1==&s2) ==> (s1==s2) [ this is the same pointers ]
s1 - is a pointer to string, or an address of string in memory. ( the same s2
is )

^^ "==" should be here.

But what the sense of this function ???
