- You cannot use the isinstance function to determine whether an object is an instance of a subclass of a class.(T/F)True or false: A class object can be passed to a function, but cannot be returned by a function.C++ Programming Assignment 6 Dynamic Pets The objective of this lab is to demonstrate dynamic allocation and deallocation of memory. Instructions: Write a class called Pet that contains an animal’s name, type, and weight. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new pet”. The destructor should print out the following message: “In the Pet destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of pets in his or her household. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Pet objects. Construct a loop in main() that executes once for each of the number of pets that the user indicated. Within this loop, ask the user to enter the name and type of pet. Using a random number generator, generate a weight between 1-100 pounds. Seed this random number generator with 100.…

(i) It must be defined inside the class (ii) It must be defined outside the class (iii) It must be defined in main function (iv) It must be defined using constructorC++ Create a class using only 1 file For each class create these features: A private variable that can only be accessed by that class. A protected variable that can only be accessed by that class or children of that class. Getter and Setter functions for accessing the private data of the class. A Constructor that outputs the name of the class whenever it is used to instantiate or construct a class object. Example : "Class A object constructed." Comments that describe exactly how the class is structured and what are it's features (superclass, subclass, overloading, etc). Add any variables or functions you deem necessary, but be sure to describe how they work using comments and the couts as required below These are the classes: Multi-level Classes consisting of 3 classes (A, B, and C, with A as top superclass). In class A, add a set of public overloading functions for printing out different data types. Example: print(int param), print(double param), and print(string param…C# Language Create a Product class then create an object from that class using User Input. The program must have Constructor.
- Home Activity Your task is to create two classes namely data and calculation. The calculation class is a friend of the data class. The data class will be composed of two floating point data members namely a and b. The class will also be composed of a friend function display that can display all the data members. Course: CSCL-1208 Object Oriented Programming Techniques The calculation class is responsible for performing operations on the data class and hence it has three functions as follows: • A function to compute the Square of sums i.e. (a + b) =a²+ b² +2ab •A function to compute the Square of difference i.e. (a - b)² =a²+ b? -2abTasks / Skills • Creating a class in C++. Steps • Create a rectangle class that has the following data o Length as a double o Width as a double Create the following methods A constructor that will initialize the data in the class The ability to set the width The ability to set the length Return the current value of the length Return the current value of the width o Return the perimeter Return the area Prints the area Create a assignment5.cpp file that contain the main() function, declares a rectangle object(s) and uses each of the methods.C++ Programming.
