Every non-static member function of a class has an implicit parameter
that is passed to the function (when called) This implicit parameter
is nothing but the "this" pointer. Now if you want to make the
implicit parameter ("this" pointer) a "const", how would u do it? This
is done by placing the "const" keyword at the end of the function
signature.
In case you want to make the "this" pointer "volatile", u can do so by
placing the keyword "volatile" at the end of the function signature.
