Question

Jimmy’s Pizza Pie shop serves a variety of pizza types, sizes and toppings. Jimmy needs a program to quickly calculate the price of a pizza that has been ordered. You will use a Pizza object in the coding of this application.

Pizza class

The following UML diagram describes members of this class:

Pizza

- crusttype:char            // stores P,D or H to indicate pan, deep dish or hand tossed crust          

- size: char                   // stores S, M or L to indicate small, medium or large pizza

- pepperoni: int            // stores number of pepperoni toppings for this pizza           

- onlonPepper:int        // stores number of onion& pepper toppings for this pizza

- cheese: bool         // indicates if there is cheese on this pizza, default is True

+ Pizza( )

+ Pizza( char ctype)

+ Pizza( char ctype, char size)

+ Pizza( bool cheeseOpt, char size = ‘M’);

+ void setCrust(char ctype)

+ void setSize(char size)

+void setCheese()

+ void setPepperoni(int quantity)

+ void setOP(int quantity)

+ char getCrust() const

+ char getSize( ) const

+ void resetToppings()

+ void noCh()

+ double calcCost( ) const

- int totalToppings() const     // note that this function is Private

+ void printToppings(ostream& out) const // prints toppings only

+ void printPizzaStats(ostream& out) const // prints crust, size, cheese, toppings

The Pizza constructor is overloaded, so that an application which is creating a new Pizza object can do so without all info initially available.

Any constructor which does is not provided with all data must use default values for the missing data. Defaults to be used:

        Crusttype => ‘P’

        Size => ‘M’

        Pepperoni => 0

        0

        Cheese => true

The set and get functions either set or return the value of the indicated member variable. The resetToppings function should reset ALL topping to their default, including Cheese. The noCh() function should set the Cheese to false.

The function calcCost returns the current cost of the pizza. The pricing is as follows:

     Pan crust : small 5    med 8    large 10

     Deep crust: small 6    med 9    large 11

     Hand tossed : small 7 med 10 large 12

    Toppings: $ 2 each         There is no change in cost if cheese is not included.

totalToppings returns the total number of toppings (cheese is not counted).

The print functions output the indicated information to the ostream object ‘out’.

The Application

Your application should:

ask the user for a crust and size

create a Pizza

ask the user for topping info (how much pepperoni, onionPepper, cheese)

print out the toppings which have been ordered

ask the user if he/she wishes to change any toppings

make changes if required

print the final PIZZA stats and cost
