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 of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.
Create the following classes based on the given declaration. Also, each class should have the default constructor. Just place the prototype of the constructors in the class but you dont have to implement them. The default constructor is a public member. A) CSUSM is an object of class University.

Create a Matrix class and implement the following member functions: The constructors and the destructor getSize() which returns the size of the matrix; setValue( int position, int value) which sets the value in the matrix at given position; getValue (int position) which returns the current value at given position; an add method which adds two matrices together; A= ● ● a subtract method which subtract two matrices together; a multiply methods which multiplies two matrices together, if possible; an overlap function which overlaps two matrices together. The augment function takes two matrices A and B of size mlxnl and m2xn2, respectively, and produce a new matrix C of size mLxnL, where mL (resp. nL) is the largest between m1 and m2 (resp. nl and n2). The values of C will either come from the original matrices by overlapping matrix B over matrix A. Wherever a value is not available it initialized to default value 0. For example: If you overlap two matrices A of size 4x2 and B of size 3x5,…
Here is a class declaration. The only member data is a vector holding ints, your job is to implement the six member functions. class IntCollection{ private: vector<int> data; public: void add(int value); int get(int index); int getSize(); IntCollection& operator=(const IntCollection &c); bool operator==(const IntCollection &c); IntCollection& operator<<(int value); }; Because a vector handles everything we need under the hood, we don't need the addCapacity function, constructors, or a destructor. The rest of the functions are described below. They should be simple to implement, most only require one or two lines! add() should add the value to the end of the vector. get() should return the element at the given index. getSize() should return the number of elements in the vector. The Assignment operator (=). The assignment operator should perform a deep copy of the argument object. It must return itself (or more…

Procedure: Develop an extension of structure.Vector, called MyVector, that includes a new method, sort. Here are some steps toward implementing this new class: 1. Create a new class, MyVector, which is declared to be an extension of the structure.Vector class. You should write a default constructor for this class that simply calls super();. This will force the structure.Vector constructor to be called. This, in turn, will initialize the protected fields of the Vector class. 2. Construct a new Vector method called sort. It should have the following declaration: public void sort(Comparator c) // pre: c is a valid comparator // post: sorts this vector in order determined by c This method uses a Comparator type object to actually perform a sort of the values in MyVector. You may use any sort that you like. 3. Write an application that reads in a data file with several fields, and, depending

The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.
Write a class Travel having two private data members (distanceCovered , Time) The class has three constructors which are • having no parameter – for setting values to zero or null. • having two parameters for assigning values to both data members. • Overload the above constructor and use this keyword to set the values of data members. • Provide getters/setters for data members. • A function which calculates and display speed of traveling. • Write a function show() displays values. Write test Application that demonstrates the Run class by calling all the three constructors and method, creating a Create Travel objects, and then display the traveling with speed. Calculate highest speed. Programming language : java
Goal 2: Creating a new "Recipe" class Member functions: A default constructor that creates an empty recipe (how will each of the member variables be initialized if there is no recipe?). A parametrized constructor that takes three arguments, a string containing the name of the recipe, a vector of strings containing the names of the ingredients, and a vector of Fractions containing the quantity of each ingredient, and assigns the attributes accordingly: Recipe(string& recipeName, vector<string>& name, vector<Fraction>& quantity); 3. A getter function called getitems that returns the number of ingredients in the recipe. Note: it also needs to be defined as const. 4. An overloaded output operator (<<) that displays the recipe name, followed by each ingredient along with their fractional quantity. See the sample output below for exact specifications. Sample Output: The product of 9/8 and 2/3 is 3/4 The quotient of 9/8 and 2/3 is 27/16 The sum of 9/8 and 2/3…
