Difference between Dot(.) and Arrow (*) in C language

Difference between Dot(.) and Arrow (*) in C language
Representation
Dot (.)					Arrow (*)
The Dot (.) operator can't be overloaded.					Arrow (->) operator can be overloaded.
ex:(*foo).bar()					ex:foo->bar()
Note1: The parenthesizes above are necessary because of the binding strength of the * and . operators.
Note2: *foo.bar() wouldn't work because Dot (.) operator binds stronger and is executed first.
Possible way of dot and arrow usage for non pointer  element in C.
ptr->fld == (*ptr).fld
str.fld == (&str)->fld
