Question 1

Wired Faculty App

List four characteristics of Object Oriented programming.

Solution

Encapsulation – Encapsulation is capturing data and keeping it safely and securely from outside interfaces.
Inheritance- This is the process by which a class can be derived from a base class with all features of the base class and some of its own. This increases code reusability.

Polymorphism- This is the ability to exist in various forms. For example, an operator can be overloaded so as to add two integer numbers and two floats.

Abstraction- The ability to represent data at a very conceptual level without any details.

Question 2

class Test:
	rollno=1
	marks=75
	def __init__(self,r,m): #function 1
		self.rollno=r
		self.marks=m
	def assign(self,r,m):     #function 2
		rollno = r
		marks = m
	def check(self):          #function 3
		print self.rollno,self.marks
		print rollno,marks

(i) In the above class definition, both the functions - function 1 as well as function 2 have a similar definition. How are they different in execution?

(ii) Write statements to execute function 1 and function 2.
