Assume a class named Collection exists. Write the header for a member function that overloads the [] operator for that class.
If a base class has a non-virtual member function named print, and a pointer variable of that class is pointing to an object of a derived class, then the code ptr->print(); calls

Using C++ Define the class called Student. The Student class has the following: Part 1) Private data members: name(string), age(int), units(int). The units represent the number of quarter units student is enrolled in. Define a default constructor as well as a constructor with parameters for the class Student. The class must have get and set functions for all private data members. The set function for the data member units must throw “out_of_range” exception if the number of units is not between 1 and 15. Include a function called tuition (double feePerUnit) that computes and returns the cost of registering for the number of units (in the private data member). The function receives the cost per unit as a parameter. Overload the operator (<<) to display student name and age. Test the class Student by writing a main program in which a Student object is created and displayed. Call the function tution(), you may pass any value as feePerUnit parameter to this function and display the…
If a base class declares a pure virtual function, a derived class must implement thatfunction to become a concrete class. T/F
Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.
The base class Pet has protected data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. Ex. If the input is: Dobby2Kreacher3German Schnauzer the output is: Pet Information: Name: Dobby Age: 2Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer #include <iostream>#include<string>#include "Dog.h" using namespace std; int main() { string petName, dogName, dogBreed; int petAge, dogAge; Pet myPet; Dog myDog; getline(cin, petName); cin >> petAge; cin.ignore(); getline(cin, dogName); cin >> dogAge; cin.ignore(); getline(cin, dogBreed); // TODO: Create generic pet (using petName, petAge) and then call PrintInfo //…
Use a member initialization list to make the GamePoints' constructor assign teamWhales with 100 and teamWolves with 100. #include <iostream>using namespace std; class GamePoints { public: GamePoints(); void Start() const; private: int teamWhales; int teamWolves;}; GamePoints::GamePoints() :/* Your code goes here */{} void GamePoints::Start() const { cout << "Game started: Whales " << teamWhales << " - " << teamWolves << " Wolves" << endl;} int main() { GamePoints myGame; myGame.Start(); return 0;}
