The function should have a class name CPizza that will have 3 constructors (default, type, copy), any public function you feel is necessary (open ended), and private member variables. There should be private data members for the three different sizes of pizza (Large, Medium, and Small), cost, a bool delivery, name, and delivery fee. The price of the pizzas are $20, $15, and $10 for large, medium, and small respectively, The cost should include the sales tax of 7,75% and a delivery fee if applicable. The delivery fee is $5 and remember it is nontaxable The most important thing is to have main do the following code to invoke the three constructors successfully CPizza order1; /I defauit constructor CPizza order2(2,1,3); type constructor for large, nediun, and small pizza CPizza order3 (order2): copy constructo /l prompt the user for erders intermation /I display completed order Get all three files (main.cpp, cpizza.h and cpizza.cpp) together in a multi-module project so it will build and run. Let me know if you have any questions fles (main.cpp. cpizza.h and cpizza.cpp) together in a multi-module project so it will build and run. Let me know if you have any questions! pe here to search
