Step by step
Solved in 2 steps
- How can code use pointers or references from the base class to execute the same virtual function so that it may be utilised across multiple data types?How we can access protected data members of a class without the use of public or private functions? Explain with codeHow should a software call a base class virtual function so that it may make use of the same virtual function in a variety of different forms and structures? A base class pointer or reference is required.
- Programming language : c++ Question : Make a class Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course.Q2\B\ True or false ( answer three) 1- Abstract data types cannot be implemented in procedural languages such as C and Pascal. 2- Although methods and fields can be static, constructors cannot be static. 3- One problem with OOP when create a Class it can never be changed. 4- polymorphysim is extensively used in implementing inheritance.Given this class specification: Class: Student Data members: int ID Write these function definitions: 1. An external definition of a member function that can be a const member function. 2. An external definition for a member function that should not be a const member function.
- Q2\B\ True or false ( answer three) 1- Abstract data types cannot be implemented in procedural languages such as C and Pascal. 2- Although methods and fields can be static, constructors cannot be static. 3- One problem with OOP when create a Class it can never be changed. 4- polymorphys im is extensively used in implementing inheritance.Objectives: The main objective of this assignment is checking students’ ability to implement membership functions. After completing this assignment, students will be able to: • implement member functions • convert a member function into a standalone function • convert a standalone function into a member function • call member functions • implement constructors • use structs for function overloading Part A: Problem description: revisiting the home decoration company assignment. Need to modify the program so the company can make some critical decisions, including processing the received inventory of art, books, furniture, and fabric. It needs the structs art, books, furniture, fabric, date, and dimension. Processing inventory: The company wants to organize its inventory by cost from least to greatest. If the price of two items is the same, either one can be displayed first. You must use a member function of the appropriate corresponding struct to perform the comparison. Lastly…6. True/False Questions: • The role of constructors is to initialize objects and data members. 1. 2. True False • A non-static member function may only refer to non-static data members of the class. 1. 2. True False All type parameters in the template prefix must appear in the body of a function template. 1. True 2. False
- Question Object Oriented Programming c++ Write a program that defines a class with a data member to holds a "serial number" for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you'll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.programming language : C++ subject : object oriented programming question: We know that an Organization consists of Managers and Employees. You are required to create a base class Person with attributes name, CNIC and gender. Derive Manager and Employee class from Person class.PROGRAMMING LANGUAGE: C++ Create a class Player with data members: first name, last name, number of matches and nationality. Derive two classes SoccerPlayer and CricketPlayer from Player.The class SoccerPlayer should have the following members: a variable to store the number of goals the player has scored and a variable to store the position on which the player plays. The class should also have a member function to compute the average number of goals scored per match.The class CricketPlayer should have variables to store the numb er of runs, thenumber of wickets and the number of catches a player has taken. Provide memberfunctions to compute the average runs scored and average wickets taken per matchby a player.Derive two classes Batsman and Bowler from the class CricketPlayer. For bats men,also store the total number of balls faced, number of 100s and number of 50s. Forbowlers, store the number of balls bowled and runs conceded. For bats men providea function to compute runs scored…
