Create an Account class in C++ that implements this UML class diagram.

C# LANGUAGE polymorphism to iterate across different employees. SEE PICTURE FOR EXAMPLE OUTPUT  Employee 1 is HourlyEmployeeEmployee 2 is PerDaymployeeEmployee 3 is MonthlyEmployee

Write program in C++ using inhertiance and polymorphism. A car dealership wants you to keep track of their sold and leased vehicles. You have realized that all vehicles have a make, model and vehicle identification number so you are going to factor those attributes out and put them in the base class as private attributes. Additionally you realize that you need to create two derived classes: one that keeps track of vehicles that are sold and the other that keeps track of ones that are leased. Vehicles that are sold have a sale date and sale amount. Vehicles that are leased have a monthly lease payment and terms of the lease (number of years). For all classes, create a proper overloaded constructor and display method that properly displays the class’s attributes. For your display method make sure you are using proper run-time polymorphism techniques so that your code calls the correct display methods. Complete main.cpp and follow comments for instruction Given code of .cpp and .h classes…

Can help with this in c++The base class is given Base: class Base { int a;double b;public:Base (int _a, double _b) : a(1), b(2.5) {}Base (int _a, double _b) :a(_a), b (_b) {}double calct () {return 1.5*a+2*b;}string toString(){return "a="+to_string(a) + "b=" + to_string(b);}};Define a class Derived, successor to Base, with an additional field d of type double. For Derived, write constructors, write a new implementation of the calc () method to add to the sum and field d with coefficient 3 and the toString () method, which returns the text description of an object of class Derived.Create objects of class Derived with the written constructors and call the two variants of the methods calc () and toString () (of the class Derived and its base class Base)
