Create the implementation file in C++ and the following: an application that declares two Cake objects and sets and displays their values. Design an application that declares an array of 250 Cake objects. Prompt the user for data for each Cake, then display all the values. Design an application that declares an array of 25 Cake objects. Prompt the user for a topping and diameter for each Cake, and pass each object to a method that computes the price and returns the complete Cake object to the main program. Then display all the Cake values. An 8-inch cake is $19.99, a 9-inch cake is $22.99, and a 10-inch cake is $25.99. Any other entered size is invalid and should cause the price to be set to 0.
