Create a class called 'Enterprize', it has one private member variable called "category" (of character type, its value is either 'F' (for food), or 'C' (for clothing), or 'H' (for housing)). This class should have constructor and accessor functions. b) Create a derived class (of Enterprize) called 'not_for_profit' having one private member variable called 'sponsor' (of character type, its value is either 'P' (for private), or 'G' (for government)). This derived class should also have constructor and accessor functions. c) Create another derived class (of Enterprize) called 'for_profit' having one private member variable called "revenue" (of integer type). This derived class should also have constructor and accessor functions. d) Define all the functions (no need of default constructors). e) In the main function, declare one object (called Salvation_army) of class 'not_for_profit' that has private sponsor and deals with clothing. Declare another object (called HEB) of class 'for_profit' that has $1M revenue and deals with food. f) Write statements to check if Salvation_army and HEB are in the same category of Enterprize or not (food, clothing, or housing) and print appropriate messages. (Friend function & Operator overloading) a) Write a friend function called 'equal' for the class 'Enterprize' that was created above. The function takes two objects of this class and compares their categories. It returns a (true) Boolean value if they are equal. Write only the function declaration and the function definition (do not write the class definition again). In the main function, write statements to compare the categories of Salvation army and HEB using the friend function 'equal' and print appropriate messages. b) Overload the '=' operator for the class 'Enterprize' that was created above. It should carry out exactly the same steps as that of the 'equal' function above. Write only the function declaration and the function definition. In the main function, write statements to compare the categories of Salvation army and HEB using the overloaded operator '==' and to print appropriate messages
