Write a C++ program that: • Implements a class with three data members {sum (int), count (int), avg (float)}.( Implement the following 3 member functions: • The first function is a default constructor which initializes sum and count to zero. (. • The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. • The third function is named outmut which drvides the sum over count and save it to avg then print the avg value). • Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbers. (

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…

Please pay attention to the required data types in the description. Thetuple, list and vector classes and their objects are not allowed to be used. 1. Define a new C++ class named “PayStub” that manages pay information: number of hours (integer), hourly pay rate (double). The total payout amount will be calculated based on overtime. Any hour that ismore than 40 hours will be paid at 1.5 pay rate. For example, with the hourly pay rate of $10.0 and if the number of hours is 40, the payout amount will be 400 and if the number of hours is 50 it will be (40 * 10)+ (10 * 15) = 550Please note that because the payout is a calculated value, it should not be part of the data members to make the object as small as possible. The class must provide at least the following two methods:• toString method that returns the string containing all the information about the paystub including the total payout amount. For example, here is the output for different paystubs:40 hours at $10.0 an hourHOURS(40)…
