Class Y is a friend of class X, which means the member functions of class Y haveaccess to the private members of class X. Does the friend key word appear inclass Y’s declaration or in class X’s declaration?
Subtask I: You will implement two classes Bid and Auction. The details are as follows: To keep things simple, each bid contains 3 attributes: bid_id: the identifer for this bid; • bidder_id: the identifer of this bidder; and auction: the identifer of this auction. ● Notice that bid_id is a unique identifier (think of a ticket) used to identify a bid whereas bidder_id identifies the person who made this made. Details about your Bid class: Your Bid class • can be instantiated via Bid (bid_id, bidder_id, auction), for example, bidtest = Bid(1, '8dac2b', 'ewmzr') provides the following access to data: If b is a Bid instance, then b. bid_id, b. bidder_id, and b. auction store this bid's bid_id, bidder_id, and auction, respectively. • has appropriate __str__ and __repr__ methods that show this bid's information. We do not specify the format. supports comparison using , ,==: two bids are compared exclusively by their bid_id. As an example, a bid with bid_id 3 is (strictly) smaller than a bid…
Write a class Teacher that contains the attribute teacher name, age and address. It alsocontains member function to input and display its attributes. Write another class Author Writeanother class Writer that contains the attributes writer name, address and number of books writtenby him. It also contains member functions to input and display its attributes. Write a third classScholar that inherits both Teacher and Writer classes. Note: Solve this using c++
Create a class Rectangle that has two data members, width and height, and two overloaded class member functions, drawshape() and drawshape(type width, type height). Show how function overloading of member function works in this class b. In the main () function, show how the object of type Rectangle access. the overloaded function.
Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add reference declarator (& before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.
Suppose that class Y is a friend of class X, meaning that the member functions of class Y have access to all the members of class X. Should the friend key word appear in class Y’s declaration or in class X’s declaration?
True or false? - In the case of class inheritance, a field initializer is just an efficient opinion for the function Object() { [native code] } of the derived class, but it is not required.
Discuss: The difference between non-member operator overloading and member operator overloading. Discuss how we can have do both of the following operations for a Car object. myCar + 5 and 5 + myCar Note: We know there is a default assignment operator fo objects. Is there any need to overload the assignment operator ever?

Create a class named Line: (a) Define private data members p1 and p2 as pointer to Point objects (the one we had in lectures), slope and length as double variables. (b) Define setter and getter functions. (c) Define a null-constructor that initializes numeric variables with zero and allocate dynamic memory for points and initialize them to [0,0] as well. (d) Overload a constructor that allocates memory for points, initilize them with given arguments, and calculate the slope and length. (e) Implement destructor, copy constructor and copy assignment operator. (f) Create a function called ”parallel” that takes too Line objects, returns true when given lines are parallel and returns false otherwise. (g) Overload the less than (<) and greater than (>) and equality (==) operators (compare the length). (h) Write a functions that reads lines in the format provided in the lines.txt from the file (without any change) and stores them in a vector named Lines. (i) Sort the objects of Lines…
