The basic goal is to make the cake and generate bill by developing a user-friendly program using 3 design patterns: Template Method, Simple Factory and Decorator pattern to formulate the task of stating procedure, constructing types and adding flavours and toppings respectively. The program is definitely open-closed principle specific. Any future accommodations and modifications are kept into the mind and the code can deliver enough scope for future engagements.
