  1. OOP involves use of the following concepts: inheritance, polymorphism, and encapsulation. What are your definitions of these terms? Why are they important? Does a program necessarily suffer if one or more of these items are absent?

Expert Solution

Encapsulation can be defined as the mechanism which takes care of :

  • Binding the data with the functionalities that manipulates it.
  • It keeps the data and the code safe from external interference

Inheritance is the mechanism by which an object acquires the some/all properties of another object. For example, a child inherits some properties of parents. Hence, this is an example of inheritance.

Polymorphism means objects have different meanings based on their data type.

In other words it means that one method with multiple implementation, for a certain class of action. And which implementation to be used is decided at runtime depending upon the situation (i.e., data type of the object).

They are important because we can relate to real work applications using these concepts. With the help of encapsulation, we can  keep classes separated and prevent them from having tightly coupled with each other. Polymorphism allows us to have multiple methods with same signatures but with different functionalities. Inheritance provides reusability of code.

No, a program need not suffer if one or more of these items are absent.

Inheritance - Polymorphism One advantage of using subclasses is the ability to use polymorphism. The idea behind polymorphism is that several different types of objects can have the same methods, and be treated in the same way. For example, have a look at the code we’ve included for this problem. We’ve defined Shape as an abstract base class. It doesn’t provide any functionality by itself, but it does supply an interface (in the form of .area() and .vertices() methods) which...
