OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

can you assign the address of an object of a derived class to a pointer to the bass class?
can you assign the address of an object of a base class to a pointer of derived class?
Step by step
Solved in 2 steps
- What must you do for classes with pointer member variables?INSTRUCTIONS: In this assignment, you will make your own smart pointer type. You will write the following class to develop a referenced counted smart pointer. You will also implement a few other member functions to resemble the functionality of an ordinary raw pointer. Basically, this is a problem of designing a single, non-trivial class and overloading a few pointer related operators. You may not use any of the STLs except for stdexcept, to do this, i.e., please dont try and use a shared_ptr to implement the class. You can start with this code, and you may add other member functions, if you want. C++ LANGUAGE Only need smart_ptr.h file.What are the three things that you are required to perform for classes that include member variables that are pointers?
- What are the three tasks you must do for classes that include member variables that are pointers?Smart Pointer: Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.PROGRAMMING LANGUAGE :C++ QUESTION; You need to store hiring date and date of birth for Managers and Employees. You need to create a Date class for this purpose. Create objects of Date class in Manager and Employee classes to store respective dates. You need to write print function in Manager and Employee classes as well to print all information of Managers and Employees. You need to perform composition to implement this task. Create objects of Manager and Employee classes in main function and call print function for both objects. ______________________________________________________________ note : print the specific part of code in following ... Print Date class here: Print updated Manager class here: Print updated Employee class here: Print main function here:
- 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…using C++ 1- Creates a class called Member with two integer x and y.a. Add a constructor able to create a Member object with tow integers and the default values 0,0.b. Add the methods setX and setY to modify the attributes x and y; [2 Markc. Add the method display able to display the attributes. 2- A Stack is a special array where the insertion and deletion will be via a specific index called "head". A Stack is characterized by 3 attributes:a. capacity (int): the maximum number element Member that can be contained into the Stack.b. head: presents the index where we can add/remove element to the Stack. The head value presents also the current number of elements into the Stack. When a Stack is created the initial value of head is 0.c. Member content[]: an array of elements of type Member. Creates the class Stack with the following methods:a. bool empty(): this method returns true if no element exists in the Stack. b. bool full(): this method returns true if there are no place to add a…C++ Q2: Write a program that defines a (value) as a base class with a set_values () function that give value to integer (val). Then define sub-class square, that calculate the square of the value squar (). In the main, define object of square (sq) and then call the functions in this object.

The point of this assignment is to work with interfaces, so you will have some specific requirements on how you solve the problem. 2) Let’s start with the sample output: a) First, the case where the user enters their own numbers: (user input in bold and red) Guess a number to demo interfaces You have 3 guesses to guess a number from 1 to 10 Do you want to make the guesses? (y/n -- if n guesses will be generated for you): y…PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes: red: int green: int blue: int You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions: changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing. printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing. You will then recreate the art program from Assignment 5 with the following changes: Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings. You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel…
