using c++ Develop a class called Point with two data members: x and y. Here you are dealing with a point in planar (2D) Cartesian coordinates with two integer values (x and y). Here are what you need to do:
• Define a print function that returns the coordinates of a Point object. • Define a function to find the distance between two points. • Define a function to move a point to the specified location (x’, y’). • Define a function to translate a point by (dx, dy): the new location will be (x+dx, y+dy). • Define functions to tell the user if a point is on the left side, right side, above, or below another point (it can be the combination of some of these or exactly on the same spot).
You also need to implement proper constructors (default and parameter constructors), a copy constructor, a destructor, getters, and setters for the data members. Implement the
Your driver program should test all member functions of the Point class thoroughly. Add file header comments and proper comments for all functions and data members.

- Each function inside the class A(n)_ is a virtual function. Provide your thoughts by filling in the blanks.arrow_forwardWrite a simple trivia quiz game using c++ Start by creating a Trivia class that contains information about a single trivia question. The class should contain a string for the question, a string for the answer to the question, and an integer representing the dollar amount the question is worth (harder questions should be worth more). Add appropriate constructor and accessor functions. In your main function create either an array or a vector of type Trivia and hard-code at least five trivia questions of your choice. Your program should then ask each question to the player, input the player’s answer, and check if the player’s answer matches the actual answer. If so, award the player the dollar amount for that question. If the player enters the wrong answer your program should display the correct answer. When all questions have been asked display the total amount that the player has won.arrow_forwardThis is in c++. Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its string argument starts with c. For example, StartsWith(’a’) is a function object that can be used as a unary predicate to determine if a string starts with an a. So, StartsWith(’a’)("alice") would return true but StartsWith(’a’)("bob") would return false. The function objects should return false when called on an empty string. Test your function objects by using one of them together with the STL algorithm count_if to count the number of strings that start with some letter in some vector of strings. So basically, I want a class that returns true or false based on if the name that is typed starts with the character that I put down.arrow_forward
- C+++ I need help filling in missing/needed code to to do the following: Read two doubles as the forceApplied and the contactArea of a BallObject object. Declare and assign pointer myBallObject with a new BallObject object using the forceApplied and the contactArea as arguments in that order. Then call myBallObject's IncreaseForceAppliedAndContactArea() member function. Ex: If the input is 3.0 2.5, then the output is: #include <iostream>#include <iomanip>using namespace std; class BallObject { public: BallObject(double forceAppliedValue, double contactAreaValue); void IncreaseForceAppliedAndContactArea(); void Print(); private: double forceApplied; double contactArea;};BallObject::BallObject(double forceAppliedValue, double contactAreaValue) { forceApplied = forceAppliedValue; contactArea = contactAreaValue;}void BallObject::IncreaseForceAppliedAndContactArea() { forceApplied = forceApplied * 5.0; contactArea = contactArea * 5.0;...arrow_forwardThe class definition for an Item is given in the image UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1: Create a class based on the specification above. Reminder: – means private and + means public. Part 2: a)Write a function/method called "addItem" that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price The function must create and add the item to the array if there is space. The function must return "true" if the addition was successful and "false" otherwise. b)Write a function/method called "listItems" that takes: An array of items The number of items in the array The function must return a string containing the information on each item in the array. c)Write a function called "pricelookup" that takes : An array of items The number of...arrow_forward
