Write a class Teacher that contains the attribute teacher name, age and address. It also contains member function to input and display its attributes. Write another class Author Write another class Writer that contains the attributes writer name, address and number of books written by him. It also contains member functions to input and display its attributes. Write a third class Scholar that inherits both Teacher and Writer classes.

Given this class specification: Class: Student Data members: int ID Write these function definitions: 1. An external definition of a member function that can be a const member function. 2. An external definition for a member function that should not be a const member function.

Using C++ and Visual Studios Using your own creativity, make a set of class templates that have these features: For this class template, put everything in one place--do not declare the member functions and have separate definition of the member functions elsewhere. Keep them in one place. Include a private variable. Include a constructor that loads the private variable when constructed. Include a destructor that clears the private variable to zero. Include set and get functions to set and get the private variable.

C++ Assignment---This is an unfinished code please complete it. Make changes if necessary. Upvote for finished working code. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do…
