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. Next, dynamically create a Pet object (remember that this requires the use of the “new” keyword which returns a pointer to the location in memory where this pet object was created.) Create each object using the default constructor of the class, and call the set functions to store the name, type, and weight of each pet. Store each Pet pointer in the array. After all of the pet objects have been constructed and added to the array, print out the contents of the array. Because the program uses dynamic memory to store the array as well as the objects in the array, be sure to de-allocate all of the memory before exiting. A sample of the program running is shown below
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
