Self-Test Exercise 17 asked you to overload the operator >> and the operator << for a class Pairs. Complete and test this exercise. Implement the default constructor and the constructors with one and two int parameters. The one-parameter constructor should initialize the first member of the pair; the second member of the pair is to be 0. Overload binary operator+ to add pairs according to the rule
(a, b) + (c, d) = (a + c, b + d)
Overload operator– analogously.
Overload operator* on Pairs and int according to the rule
(a, b) * c = (a * c, b * c)
Write a program to test all the member functions and overloaded operators in your class definition.

- To avoid making private types public, explain why accessors are better in each of the following three cases.arrow_forwardWhat is polymorphism, and how does it affect you? How can operator overloading help with polymorphism? Explain it by concatenating two strings with the '+' operator.arrow_forwardExplain why it is better to have accessors for private types rather than public types in no more than three sentences.arrow_forward
- In C++, How can I use and apply using templates in my programming assignments? Such as how and when to using templates? Because, I know how to implement them, and theoratically to why we use them, but I am not sure how can I use this in code that involves in polymorphism, such as for example lets say we have a class called player and another class called Roles, and lets say that class Roles is to inherit from Player. How would I use templates in this case? Or even in some cases what is the mindset or logical thinking should I have when developing code involving templates?arrow_forwardassume that the class student with private members id,name, number of courses,*p (a pointer of type int) has been already defined. implement the set() function and the copy constructor of the classarrow_forwardCreate a class Reverse with one data member called num of type int and a static method find to return reverse of num. Create a subclass ReverseR from Reverse which overrides member of its super class. Write a main() method that tests in same class ReverseR. method find()) and this override method uses recursion to find and returns reverse of dataarrow_forward
- Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…arrow_forwardCreate a Pair class that encapsulates two objectsof the same data type in an instance of Pair.arrow_forwardQ> Can we inherit Constructors or not?arrow_forward
- Given these three arguments, please explain why it is better to have accessors for private types rather than making them public.arrow_forwardClass Y is a friend of class X, which means the member functions of class Y haveaccess to the private members of class X. Does the friend key word appear inclass Y’s declaration or in class X’s declaration?arrow_forwardjava singly linked list use the template below to solve the problem USE THE TEMPLATE!!!!!!!!!!!!!!! public class Citizen{ //Create your list of attributes/variables here //Your default constructors goes here public Citizen(){ } //Your accessors and mutators goes here /* EXAMPLE: Pls delete ************* public int getSomething(){ return idk; } public void setSomething(String newWord){ oldWord = newWord; } ************** */ //Your toString() method goes here public String toString(){ return ""; } //Your main method goes here to test for class implementation public static void main(String[] args){ System.out.println("Hello Students"); }} 1.
