Give advantages and disadvantages of using OOP over procedural programming
Advantages - Classes and objects promote a lot of code reuse
- Allows new classes to extend old ones reducing duplication of code
Disadvantages - Can be complicated to learn due to many concepts e.g. inheritance, encapsulation, polymorphism etc.
Give advantages and disadvantages of using procedural programming over OOP
Advantages: Easy to understand
- Its quicker to write smaller programs as you don't need to define classes ond objects
Disadvantages: There's more code repetition (even with subroutines)
