Answer #1

Code Refactoring is a process of changing the structure of the code without changing the output.

a) Postfactoring

The functions are defined for what they should do.

Moving the function after function body definition is postfactoring.

b) Prefactoring

The actualization of method is required, and in order to represent the subclasses the superclass has to be modified. As the modification takes place before the actualization the superclass is prefactored.

c) Prefactoring

The code needs to be organized properly before implementing the methods. Thus, this is prefactoring.

d) Postfactoring

  After the class definition is completed , all the methods are fully implemented, then only the classes are merged. Hence, we call it postfactoring.
