Step by step
Solved in 2 steps with 1 images
- first, define the rectangle class which has two functions for calculating area and perimeter. then write a c++ program that in its main function has 2 square objects and calculate their area and perimeter. for each object ask the user to give you the sides. in your class definition write a comment to tell which function is mutator, which function is accessor, which one is the constructor.Write a running C++ code for a class named Student that make use of the public and private functions to print the following message” Only active students will pass the module”Write a C++ class to represent an Employee. Each employee is given a name, an age, a NIC number, anaddress, and a salary. Furthermore: The Employee class should keep track of how many employees (objects) have been created inthe system. Your Employee class should initialize all of its fields via a constructor. Create function prototypes to set and get an employee's zip code. Declare a print_employee() function that prints all of an employee object's details.(Whenever possible, use constant functions.)
- A constructor is like a function. It can return any type value needed.t or f?QUESTION 10 _____ is used to create an object. A. In-built functions B. constructor C. class D. User-defined functionsCreate parent class Shapes with protected parameters width and height and function printarea() and a virtual function cal_area(). Create two sub classes Rectangle and Sqaure. In main() create 2 pointers of Shapes and assign Rectangle and Square to it. Call printarea function with the pointers. Note: Use C++ language with well explaination. After performing this program. Implement this program using an abstract class.
- Write a java program that contains variables to hold employee data like; employeeCode, employeeName and date Of Joining. Write a function that assigns the user defined values to these variables. Write another function that asks the user to enter current date and then checks if the employee tenure is more than three years or not. Call the functions in main. Now write a runner class that declares two employee objects and check their tenure periods.Make a class Distance having a member meter. Now create a friend function named convert() that increments meter by 5 and then convert that meter in kilo meters and return the answer. Call the function in main. Note: Solve as soon as possible Use C++ Language Soloution must be well explained with double lines commentsCreate a class personAge with following data members: name, dob, age. Calculate age by taking name and dob as input from user. Make appropriate static/constant functions and variables. Note: Solve as soon as possible Solve this program in C++ language using OOP concepts
- Create class Employee that has the following pieces of information called first name, last name, day off and salary. Write a C++ program to implement the following functions for three employees: 1- Constructor to initialize data members. 2- Set and get functions for data members 3- Operate decrement operator to decrement the salary when the employee has a day off. 4- Display the results using friend function called Display().Please written by computer source How should each type of variable be passed to a function under the parenthesized situation? One answer will be used twice . Group of answer choices string (changes parameter) [ Choose ] double (doesn't change parameter) [ Choose ] user-defined class object (doesn't change parameter) [ Choose ] int (changes parameter) [ Choose ] options by value by reference (no const) by reference to constant objectWrite the definitions of the member functions of the class calendarType (designed in Programming Exercise 9) to implement the operations of the class calendarType. Write a test program that accepts the number of a month (1 - 12) and the year from the user as input and prints the calendar for that particular month and year.
