Question

What would you need to do to turn your program into an Object Orientated program?

Answer 1

OOP is used, when a programmer needs to operate with a lot of similar objects. If I needed to turn my program into OOP program, I would need to entirely reorganize its architecture: write class, decide on attributes of objects, write them, write accessors and other methods, decide on inheritance, decide on usage of interfaces, decide on overloading operators and so on.
