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:
Step by step
Solved in 3 steps
- Class Implementation Exercises EX1: Write a complete C++ program to implement a car class. The class has three attributes: Id, speed and color. Also, the class include the following methods: (setter) function, (getter) function, (default and parameterized constructor), and( print) to print the attributes values ➜ Create three objects in the main function then call the method. EX2: Write a complete C++ program to implement a student class. ➜ The class has three attributes:std-Id, Name and marks [3]. Also, the class include the following methods: (setter) function,(getter) functions (default and parameterized constructor), (average) and(print) to print the attributes values ➜ Create array of objects in the main function then call the method.C++ True/False: a member function in a class can access all of its class's member variables, but not if the variables are private.Differentiate between constructor and destructor function in context of classes and objects using C++
- TRUE OR FALSE: In C++, comments that begin with the "multi-line" comment symbol can't be nested. A member function of a class has access to only the public data members of the class. If a C++ function does not take any parameters, parenthesis around the empty parameter list are still required. The size of a pointer variable depends on the type that it is pointing to.In C++, if a member of a class is private, we cannot access it outside the class, but what if the member variable is protected?C++ The class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class. Input should be format month day year with each separated by a space. If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a message indicating that it is not a leap year. Header file: #ifndef date_H #define date_H class dateType { public: void setDate(int month, int day, int year); //Function to set the date. //The member variables dMonth, dDay, and dYear are set //according to the parameters…

The parameter and return type s of each function and class member function should be decided in advance. The program will be best implemented as a multi-file program, (header file, the main program,..) Design a generic class to hold the following information about a bank account: Balance Number of deposits this month Number of withdrawals Annual Interest Rate Monthly service charges The class should have the following member function: Constructors Accepts arguments for the balance and annual interest rate. deposit a virtual function that accepts an argument for the amount of the deposit. The function should add the argument to the account balance. It should also increment the variable holding the number of deposits. withdraw a virtual function that accepts an argument for the amount of the withdrawal. The function should subtract the argument from the account balance. It should also increment the variable…
- In C++ Write a c++ program to count the number of objects created and destroyed for a class using static data members and static member functionsC++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.What do you understand by static data member and static memberfunction?(IN C++)
