CS304 Object Oriented Programming

1st Lecture


............... is a technique in which we visualize our programming problems in the form of objects and their interactions as happen in real life

• OOP
• Object
• Object orientation
• Structure

............ makes it easier for us to solve our real world problems through programming in terms of real world object.

• Object Orintation
• OOP
• Data Structures
• None of above

A ........... is an abstraction of something real or conceptual.

• Oop
• Object
• Model
• Structures

Advantages of OOP are ..............

• Easy,linear
• Hard, fast
• Develop, understandable
• All of above

Object is a ...................... thing.

• Tangible
• Pure
• Original
  
• None of Above

Oop is used because it is closer to ...............

• Objects
• Data structures
• Reality
• Programming

Object orientation is achieved using objects and their .................

• Functions
• Relationships
• Structures
• None of above

Objects may be tangible or intangible.

• True
• False

There may more than one aspects of an object.

• True
• False

................. is the abstraction of some real world scenario. It helps us to understand that scenario.

• OOP
• Object
• Object orientation
• Model

Lecture No 2.


Information hiding is achieved in OOP using

• all information related to an object is stored within the object.
• it is hidden from the outside world.
• it can only be manipulated by the object itself
• all of above.

advantages of information hiding

• it simplifies our OO model
  
• it is a barrier against change propagation
  
• option (i) & Option (ii)
• None of above

we have enclosed all the characteristics of an object in the object itself.

• information hinding
• OOP
• encapsulation
• OO Model

information hiding and encapsulation are very ................... concepts.

• common
  
• distributed
• related
• easy

advantages of encapsulation.....

• low complexity
• simplicity and clarity
• better undrestanding
• all of above

................. is a set of functions of an object that he wants to expose to other objects.

• Model
• OOP
• encapsulation
• interface

The number and kind of messages that can be sent to an object depend upon its....

• Model
• message
• interface
• none of above

An ........ may have more than one interface...

• message
  
• object
• stimulus
• model

................ and implementation are separated from from each other to achieve information hiding.

• model
  
• message
• encapsulation
• interface
  

Objects communicates with each other using ......

• message
• model
• data structure
• none of above
