Advantages of OOP

Object-Oriented Programming has the following advantages over conventional approaches:

OOP provides a clear modular structure for programs which makes it good for defining abstract data types where implementation details are hidden and the unit has a clearly defined interface.

OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.

OOP provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer.
