Actually, few C++ programmers would write (*cptr).radius or
(*cptr).volume ( ). Instead, most would take advantage of the
class-pointer operator, ->, which you can think of as a
shorthand that takes the place of both the dereferencing operator and the
class-member operator. Thus, the following are equivalent:
Equivalent
(*cptr).radius <----------> cptr -> radius
The following are also equivalent:
Equivalent
(*cptr).volume ( ) <----------> cptr -> volume ( )
Thus, the class-pointer operator takes the place of two other operators and eliminates the need for precedence-defeating parentheses.
