Define a class, named Vector, that represents a vector of coordinates (x,y). In the Vector class, define (not declare) the following inline functions (defined within the class, no separation of .h and .cpp files): a. A default constructor that initializes the vector as (0, 0). b. An overloaded constructor that takes in two double values (a and b) as arguments and initializes the vector as (a, b). c. A function dotProduct that takes in two vectors (m and n) as arguments, performs dot product with m and n, and returns the result as a double. Use the fact: (a, b) · (c, d) = (a x c) + (b × d). Be aware the type of m and n when you declare the function (hint: they are not double). class Vector public: double x, y; // define your default constructor here //define your overloaded constructor here // define your dotProduct here

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Define a class, named Vector, that represents a vector of coordinates (x,y). In the Vector class,
define (not declare) the following inline functions (defined within the class, no separation of .h and .cpp
files):
a. A default constructor that initializes the vector as (0, 0).
b. An overloaded constructor that takes in two double values (a and b) as arguments and initializes
the vector as (a, b).
c. A function dotProduct that takes in two vectors (m and n) as arguments, performs dot product
with m and n, and returns the result as a double.
Use the fact: (a, b) · (c, d) = (a x c) + (b × d). Be aware the type of m and n when you declare
the function (hint: they are not double).
class Vector
public:
double x, y;
// define your default constructor here
//define your overloaded constructor here
//define your dotProduct here

Write 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.
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…

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 //…
