Dear Students,
You have studied about different features of OOP in this course. You also did learn about different relationships between objects and classes. Inheritance and Aggregation are important of those. Now you have to give your views in favour or against the phrase while considering coupling and choesion 03 - 05 concrete points for justifying your answer:

Aggregation is more suitbale while designing a system using OOP

or

Inheritance is more suitable while designing a system using OOP

Idea

In object-oriented programming (OOP), Inheritance is a way to compartmentalize and reuse code by creating collections of attributes and behaviors called objects which can be based on previously created objects. In classical inheritance where objects are defined by classes, classes can inherit other classes. The new classes, known as Sub-classes (or derived classes), inherit attributes and behavior of the pre-existing classes, which are referred to as Super-classes (or ancestor classes). The inheritance relationship of sub- and superclasses gives rise to a hierarchy. In Prototype-based programming objects can be defined directly from other objects without the need to define any classes.
