Use separate compilation to declare a class Employee as an ADT. Remember to include the necessary directives.

The class Employee has two member variables,

name $($a string$)$ and

salary $($a double value$).$

Provide only the class declaration $($interface$)$ for the class Employee. The class Employee has the following member functions:

a default constructor

a destructor

a mutator for the member variable name

an accessor for the member variable salary

an overloaded comparson operator $>($implemented as a friend function$)$ with the following prototype:

bool operator$>($const Employee & E$1,$ const Employee & E$2)$

This function returns true if $E1\text{'}$s salary are greater than $E2\text{'}$s salary and fal se otherwise.

an overloaded stream extraction operator for the class Employee.
