In this exercise, you modify the Pete’s Pizzeria application from this chapter’s Focus lesson. Use Windows to make a copy of the Pizzeria Solution folder. Rename the copy Pizzeria Solution-Default. Open the Pizzeria Solution.sln file contained in the Pizzeria Solution-Default folder. Open the Code Editor window and locate the btnCalc_Click procedure. Modify the procedure so it uses the Rectangle class’s default constructor (rather than its parameterized constructor) when instantiating the entirePizza and pizzaSlice objects. Save the solution and then start and test the application.
