In C++ with comments and follow the instructions please

here is the question :

Thanks in advance

Pizza Ordering System This lab uses vectors in TWO wavs A list of pizza orders (in the "app") A vector INSIDE the class to keep a list of pizza toppings Make sure you have a clear vision of this before you start coding. READ THE INSTRUCTIONS SEVERAL TIMES Implement this lab with THREE files (pizza.h, pizza.cpp, app.cpp) PizzasRUs needs a system to create and process customer orders. They sell pizzas in 3 sizes small, medium, large. The user can add as many toppings as they like. Pizza pricing: Small = 10, medium = 14, large = 17 Plus S2 for each topping Create a class called Pizza that can be used to process pizza orders. Required class attributes and functions are as follows Class attributes Customer name (you can make it a single name, no spaces) Size of pizza (you decide whether to use string or char) A VECTOR of strings that represents the toppings Class Functions Default constructor set/get for size (validate that size is only S, M, L- any case) set/get for name addTopping -this function receives a string representing a topping, adds to to the vector in the class * clearTopping - this function resets the topping vector to empty (use .clear() function) getPrice - this function calculates are returns the price of the pizza display - this function displays the pizza order in the format shown in sample output Make sure you code AND TEST EACH CLASS FUNCTION FIRST. If they all work correctlv, it will be simple to "build" the app
