in c++ programing

hi

please send me the C++ code for this problem

thank you

In this task single inheritance with static and dynamic binding shall be trained. For this a simple and extendable electronic shopping ple articles smart phones, notebooks and accessories shall be ordered (due to clarity in the UML class diagram below data types, parameters and destructors are omitted.) task 1 Define an abstract base class for an offered article with name Article. This class shall have following members: a private string attribute with name model storing the article model name. two private real valued attributes with names netprice for the net price and tax Rate storing the tax value in percent of the article. a public constructor with three parameters to initialise the attributes of an object; the tax rate shall be a default parameter with 19 a virtual public destructor producing an output "Article)" at its call and the article model name (see examples below). a public method with name set_model assigning a string parameter to the model name attribute a public method with name set_netPrice assigning the double parameter to the net price attribute. a public method with name get model without parameters returning the model name as function value. a public method with name get_netPrice without parameters returning the net price as function value. a public method with name get grossPrice without parameters returning the gross price (gross price = net price + tax) as function value a pure virtual public method with name print without parameter or return value. task 2 Define a class with name Accessory derived from abstract class Article. This class shall have following members: a private Boolean attribute with name original for an original accessory. a public constructor with three parameters for the article name, the net price and whether it is an original accessory with true as default parameter. The tax rate shall be automatically initialised by the default parameter of class constructor Articlea virtual public destructor producing an output Accessory("at its call (see examples at the bottom). a virtual public destructor producing an output Accessoryo" at its call (see examples at the bottom). a virtual public method with name print without parameters writing the article name and original accessory)", if it is an original one (see examples at the bottom). task 3 Define a C++11 enumeration class with name OperatingSystem and enumeration values unknown, android, iOS, macos, linux, proprietary, unix and windows. Define an overloaded output operator
