Advantages and Disadvantages of OOP

Advantages of OOPs

Object oriented programming contributes greater programmer productivity, better quality of software and lesser maintenance cost. 

The main advantages are:

  1. Making the use of inheritance, redundant code is eliminated, and the existing class is extended.
  2. Through data hiding, programmer can build secure programs that cannot be invaded by code in other parts of the program.
  3. It is possible to have multiple instances of an object to co-exist without any interference.
  4. System can be easily upgraded from small to large systems.
  5. Software complexity can be easily managed.
  6. Message passing technique for communication between objects makes the interface description with external system much simpler.
  7. Aids trapping in an existing pattern of human thought into programming.
  8. Code reusability is much easier than conventional programming languages.


Disadvantages of OOPs

  1. Compiler and runtime overhead. Object oriented program required greater processing overhead – demands more resources.
  2. An object’s natural environment is in RAM as a dynamic entity but traditional data storage in files or databases.
  3. Re-orientation of software developer to object-oriented thinking.
  4. Requires the mastery in software engineering and programming methodology.
  5. Benefits only in long run while managing large software projects.
  6. The message passing between many objects in a complex application can be difficult to trace & debug.

C Program for SCAN Disk Scheduling Algorithm | C Programming

Image
Introduction to SCAN disk scheduling :                    In the SCAN algorithm, the disk arm starts at one end of the disk and moves toward the other end, servicing requests as it reaches each cylinder, until it gets to the other end of the disk. At the other end, the direction of the head movement is reversed, and servicing continues. The head continuously scans back and forth across the disk. The SCAN algorithm is sometimes called the elevator algorithm, since the disk arm behaves just like an elevator in a building, first servicing all the requests going up and then reversing to service requests the other way.

C program to Find Cartesian Product of Two Sets | C programming

Image
C program to find the Cartesian Product of two sets   Cartesian product  is a mathematical operation that returns a set (or  product set  or simply  product ) from multiple sets. That is, for sets  A  and  B , the Cartesian product  A  ×  B  is the set of all ordered pairs  ( a ,  b )  where  a  ∈  A  and  b  ∈  B . Products can be specified using set-builder notation, e.g. {\displaystyle A\times B=\{\,(a,b)\mid a\in A\ {\mbox{ and }}\ b\in B\,\}.}
