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:

- I've gotten stuck on this practice problem. I need help figuring this out. You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the hungry level of the pet to 0 (Full) You must…Consider the following class and answer questions after this class #include <string> using namespace std; class Account { public: Account(string accountName, int initialBalance) { name=accountName; if (initialBalance > 0) { balance = initialBalance; } } void deposit(int depositAmount) { if (depositAmount > 0) { balance = balance + depositAmount; } } int getBalance() const { return balance; } void setName(string accountName) { name = accountName; } string getName() const { return name; } private: string name; int balance; }; a) Rewrite the above class.

I will attach a screenshot of my program and here are the instructions: In your program define a class called GeoPoint that will have the following: A constructor __init__(self, lat=0, lon=0,description=’TBD’) that will initialize the class variables called: self.lat, self.lon, and self.description. A SetPoint(self, point) method that takes an individual points coordinates as a single sequence and sets them to self.lat, self.long. E.g: self.lat = point[0] self.lon =point[1] A GetPoint(self) method that will return a tuple or list with self.lat, self.lon.

Based on the above class definition, provide the derived classes below that will override the function cage_size from the base class Animal: i.Elephant, cage_size = 1.5 x length x height ii.Giraffe, cage_size = 2.5 x length x height B. Write the complete main () function that will create the object Elephant and Giraffe. Insert their length and height to calculate their cage_size. Note: A virtual function is a member function which is declared within a base class and is expected to be re-defined (overridden) by a derived class.
