Consider the following class implementation, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } bool operator!=(Price); bool operator<(Price); }; Write an implementation for both overloaded operators. != should return true if the Prices are not equivalent, and should return false if they are equivalent. < should return true if the Price of the calling object (left object) is less than the parameter Price object (right object). You do not need to demonstrate calling these operators

Classes define new types in C++. Types in C++ not only interact by means of constructions and assignments but also via operators. For example: int a=2, b=1, c; c = b + a; The result of variable c will be 3.Similarly, classes can also perform operations using operator overloading. Operators are overloaded by means of operator functions, which are regular functions with special names. Their name begins with the operator keyword followed by the operator sign that is overloaded. The syntax is: type operator sign (parameters) { /*... body ...*/ } You are given a main() function which takes a set of inputs to create two matrices and prints the result of their addition. You need to write the class Matrix which has a member a of type vector<vector<int> >. You also need to write a member function to overload the operator +. The function's job will be to add two objects of Matrix type and return the resultant Matrix. Input Format First line will contain the number of test…
Exercise on class inheritance in C++. General requirements: • All data members must be declared as “private” • No global variable is allowed to be declared and used (constants are ok) • Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and return value instead unless it is stated explicitly. • “cin” and “cout” should be used in main() or any testing functions • Please make sure that you clearly show how the C++ class, its methods and all the functions are being called and print out its return value and its results properly Please answer the following questions. 1. Define a class named “BooleanVariable” that manages a variable name (string) and a boolean value (true or false). It should not have default constructor. The class must at least provide the following methods: - toString() method that can return a string in the following format: variable-name(variable-boolean-value) such as isSuccessful(true) -…
THIS NEEDS TO BE DONE IN C#! Modify the code below so that the base class is an abstract class. class Pokemon{ protected string Name; protected string Type; protected string Health; public override void Attack() { //body of Attack } } Make Attack abstract as well. You do NOT have to create a derived class.
For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…
In C++, write a Number class that holds a double, and add overloaded operators for +, –, *, /, and assignment. Choose the return values for these functions so that expressions can be chained together, and for efficiency. Write an automatic type conversion operator intdouble( ).

C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…
Method overriding is combination of inheritance and polymorphism? T/F
In C++ Write the implementation (.cpp file) of the Counter class of the previous exercise.The full specification of the class is: A data member counter of type int. An data member named counterID of type int. A static int data member named nCounters which is initialized to 0. A constructor that takes an int argument and assigns its value to counter. It also adds one to the static variable nCounters and assigns the (new) value of nCounters to counterID. A function called increment that accepts no parameters and returns no value. increment adds one to the instance variable counter. A function called decrement that accepts no parameters and returns no value. decrement subtracts one from the counter. A function called getValue that accepts no parameters and returns an int. It returns the value of the instance variable counter. A function named getCounterID that accepts no parameters and returns an int. getCounterID returns the value of the data member counterID.
(Using C++) Define a base class vehicle and its two derived classes :Car and Scooter. Write a program to ask the user for the type of vehicle and then using the concept of runtime polymorphism, display the message "It is a two-wheeler" for scooter and "It is a four-wheeler" for car.

Help of what these errors mean. In C# • Create a Class, named Student, to hold properties of Student Last Name, Student First Name, Student ID (9 digits), Course Prefix and Number, and the tests (Test 1, Test 2, Test 3, Test 4). Create appropriate setter and getter accessors, and constructors. Use access modifiers. Example: First Name : Pat Last Name : Smythe Student ID : ABC111333 Course Prefix : CIST Course Name : 2431 Test 1 : 100 Test 2 : 90 Test 3 : 80 Test 4 : 88 • Prompt the user for the Student Last and First Name, Student ID, Course Prefix and Number and the tests. • Include at least one exception handling function. • Use an array to store the 4 test grades. • Use a looping structure to populate the array. • Calculate the numeric average based upon the 4 equally-weighted numeric grades. • Display all the data for each of student using a looping structure. • Display the numeric average for each student. • Create a function that will convert the numeric average to a…
