- In C++, write a Employee class with id, name and salary; declare 3 dynamic objects (pointer and new keywords) and push them to the vector and print the vector.write a class implementation using C++ from the given class diagram TAKE NOTEOF THE FF SPECIFICATIONS: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. Please note that the deactivated voter account must be still part of the “object”. Test all the functions by making calls. this should be the sample result. Please use simple codes only.WRITE IN C++ A Date class is described by month(m), day(d), year(y). An Employee is described by a unique data structure having a name (e.g. “George”), salary(75000.25) and date_of_birth (06, 10, 1998). Calculate the number of days between his day of birth and (09, 20, 2023). Assume that the Employee object contains a Date sub-object)
- Writing in C++, using <iostream>, using (Pointers), (Concrete and abstract class), (Overloaded functions and constructors), (Inheritance), (Polymorphism), Write a program that user can add lists of ordered food, then user give program information if ordered food delivered, then program shows inventory(delivered food) and food that did not delivered yet.Write a C++ program to add new details in the existing ArrayList and to remove details from the ArrayList. Use Menu to add, remove and display the Hall details. Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names and function names should be the same as specified in the problem statement. Create Hall class with private member variables Data type Variables string name int contactNumber double costPerDay string ownerName Include appropriate getters, and setters and constructor (name,contactNumber,costPerDay,ownerName) in this order for the Hall class. Include following public member function in Hall class Method Name Description list<Hall> getHallDetails() This method is used to return the hall details.[Hall details are already pre-populated in the template code] Create HallBO class and include following member function Method Name Description…Write a program in C++, that creates a class Rock with a default constructor, a copy-constructor, an assignment operator, and a destructor, all of which announce to cout that they’ve been called. In main( ), create a vector<Rock> (that is, hold Rock objects by value) and add some Rocks. Run the program and explain the output you get. Note whether the destructors are called for the Rock objects in the vector. Now repeat the exercise with a vector<Rock*>. Is it possible to create a vector<Rock&>?
- Write a program in the C++ language to create a class Rectangle with two member integer variables length and breadth. Write the parameterized constructor for the class and also add a member function that displays the area of the rectangle in the output.//Write C++ program to creat a class named (City) which includes function getName, getPop and displayInfo to enter and display the information (names and population) of 4 cities using array of objects.Develop an algorithm and write a C++ program that counts the letter occurrence in the string; make sure you use call by reference to the array of a class with letter and count as private member attributes when return from parse function. For the class member methods, provide the public accessor and modifier as well as print functions for the private member attributes. Write a test program that reads a C-string and displays the number of letters [a-z] and number of numbers [0-9] in the string. In addition to that, you need to output the histogram of the letter and count array. Here is a sample run of the program: <Output> Enter a string: 2023 is coming The number of letters in 2023 is coming is 8 The number of numbers in 2023 is coming is 4 ---- Histogram ---- Char Count 0 1 2 2 3 1 c 1 g 1 i 2 m 1 n 1 /* not a completed output */ <End Output>
- Write a C++ program to create a new date by the user. The user will type in month, day, and year with a function called readDate( ) with appropriate parameters. Define a class called Date, with month, day, and year as private members with integer values, and a public member function, setDate( ), which will set the input dates, and showDate( ) to display the input date as an output for the class.write a program c++ Define a class rectangle with the following data members: L,W and the following memelber functions: 1. Set_data that stores parameters values into data members. 2. Area that returns the area of the rectangle. 3. Ret_Lw that returns the length and width of the rectangle. # Let your main Function declares two objects of the length (L) and the width (W) of the rectangle of largest area.Solve the problem in C++ (Extend MyPoint) In Programming Exercise 9.4, the MyPoint class was created to model a point in a two-dimensional plane. The MyPoint class has the properties x and y that represent x- and y-coordinates, two getter functions for x and y, and the function for returning the distance between two points. Create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features: - A data field named z that represents the z-coordinate.- A no-arg constructor that constructs a point with coordinates (0, 0, 0).- A constructor that constructs a point with three specified coordinates.- A constant getter function that returns the z value.- A constant distance(const MyPoint&) function to return the distance between this point and the other point in the three-dimensional space. Draw the UML diagram for the classes involved. Implement the classes. Write a test program that creates two…
