Write class declaration for a class named Pizza that has the data members price, a double, and size, a Circle object. It also has member functions: setPrice () which sets the data member price, setSize() which sets the Circle data member, and costPerSqln() which returns the double value that is the cost per square inch of the pizza. Write code for these as inline functions. Your Pizza class will also need to have a default constructor which has no parameters and sets the price to $5.00 and the size to a radius of 6. It will also have another constructor which accepts two parameters: P for price and S for size. Write a main() program that makes two Pizza objects to test out the two constructors. The main() program also needs to test out the set Price(), setSize(), and costPerSqln() member functions.
