You are defining A class for use in a program you are writing. Which of the >>>>ADD: “a” lowwercse following should be placed in the interface file for your class? Which should be placed in the implementation file for your class?

a) The class definition.
b) The declaration of a stand-alone function (neither member nor friend of the class)
that uses this class type parameter, and is used as a class operation.
c) The declaration of a stand-alone overloaded operator (neither member nor friend
of the class) that is to serve as a class operation.
d) The definition of a stand-alone function (neither member nor friend of the class)
that uses this class type parameter, and is to serve as a class operation.
e) The definition of a friend function that is to serve as a class operation.
f) The definition of a member function.
g) The definition of a stand-alone overloaded operator (neither member nor friend of the class) that is to serve as a class operation.
h) The definition of an overloaded operator that is to serve as a class operation and is a friend of the class.
i) The main function of your program.

The interface file should include a) b) and c). Parts d) through h): All
definitions of any sort go into the implementation file. Note that the class definition
must also go into the implementation file. It is a good practice to #include the
interface in the implementation file. Part (i), the main function goes into the
application file.
