- c++ Implement a BankAccount class. BankAccount must have the following members: A member variable account_no of the type unsigned int.A member variable owner_name of type std :: string.A member variable balance of the double type.A parameterized constructor that takes account_no and owner_name as input parameters.The members must be encapsulated in accordance with the usual convention. Overlay the inflow operator (>>) for the BankAccount class Input follows the format:[account_no] [owner_name] [balance] and must be loaded with the inflow operator. Output should have the following format:Account [account_no], owned by [owner_name] has the balance [balance] Note that the square brackets refer to variables or special characters and are not included.You may add necessary designers, member functions and operators at will as long as they are appropriate. input expected output123 Hansson 1000 Account 123, owned by Hansson has the…For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…in c++ write aprogram to Create a class Rectangle with length and breadth as private data members and also provide the following member functions: getdata(): gets the length and breadth of rectangle. calarea(): return the area of the rectangle. calperi(): return the perimeter of the rectangle. issquare(): return true if the rectangle is square
- Answer this in C++: In the Student.cpp file and Student.h file, build the Student class with the following specifications: Private data members string name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member functions SetName() - sets the student's name GetName() - returns the student's name SetGPA() - sets the student's GPA GetGPA() - returns the student's GPA Ex. If a new Student object is created, the default constructor sets name to "Louie" and gpa to 1. The output of GetName() and GetGPA() before and after calling SetName("Felix") and SetGPA(3.7) is: Louie/1 Felix/3.7 main.cpp #include <iostream> #include <vector> #include "Student.h" using namespace std; int main() { Student student = Student(); cout << student.GetName() << "/" << student.GetGPA() << endl; student.SetName("Felix"); student.SetGPA(3.7); cout <<…C++ QUESTION 2. Give a definition for a class InternationalStudent that is a derived class of the base class Student given in the following. Do not bother with #include directives or namespace details.class Student{public:Student( );void printInfo( ) const;protected:int id;string name;};This class InternationalStudent should have an additional data field nation of type string ; one additional member function isFunded that takes no arguments and returns a value of type bool ; and suitable constructors.You do not need to give any implementations, just the class definition.Create 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.

Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Modify the above classes and provide overloaded constructor implementation for each class.
