Benefits of OOP (object oriented programming)

OOP offers several benefits to both the program designer and the user. Object-Orientation contributes to the solution of many problems associated with the development and quality of software products. The new technology promises greater programmer productivity, better quality of software and lesser maintenance cost. The principal advantages are:


  • Through inheritance, we can eliminate redundant code extend the use of existing classes
  • We can build programs from the standard working modules that communicate with one another, rather than having to start writing the code from scratch. This leads to saving of development time and higher productivity.
  • The principle of data hiding helps the programmer to build secure program that can not be invaded by code in other parts of a programs.
  • It is possible to have multiple instances of an object to co-exist without any interference.
  • It is possible to map object in the problem domain to those in the program.
  • It is easy to partition the work in a project based on objects.
  • The data-centered design approach enables us to capture more detail of a model can implemental form.
  • Object-oriented system can be easily upgraded from small to large system.
  • Message passing techniques for communication between objects makes to interface descriptions with external systems much simpler.
  • Software complexity can be easily managed.


While it is possible to incorporate all these features in an object-oriented system, their importance depends on the type of the project and the preference of the programmer. There are a number of issues that need to be tackled to reap some of the benefits stated above. For instance, object libraries must be available for reuse. The technology is still developing and current product may be superseded quickly. Strict controls and protocols need to be developed if reuse is not to be compromised.

Application of OOP

OOP has become one of the programming buzzwords today. There appears to be a great deal of excitement and interest among software engineers in using OOP. Applications of OOP are beginning to gain importance in many areas. The most popular application of object-oriented programming, up to now, has been in the area of user interface design such as window. Hundreds of windowing systems have been developed, using the OOP techniques. Real-business system are often much more complex and contain many more objects with complicated attributes and method. OOP is useful in these types of application because it can simplify a complex problem. The promising areas of application of OOP include:  Real-time system  Simulation and modeling Object-oriented data bases Hypertext, Hypermedia, and expertext AI and expert systems  Neural networks and parallel programming Decision support and office automation systems  CIM/CAM/CAD systems  The object-oriented paradigm spra...

Simple C++ Program

Image
Let us begin with a simple example of a C++ program that prints a string on the screen. This simple program demonstrates several C++ features. Program feature Like C, the C++ program is a collection of function. The above example contain only one function main(). As usual execution begins at main(). Every C++ program must have a main(). C++ is a free form language. With a few exception, the compiler ignore carriage return and white spaces. Like C, the C++ statements terminate with semicolons. Comments C++ introduces a new comment symbol // (double slash). Comment start with a double slash symbol and terminate at the end of the line. A comment may start anywhere in the line, and whatever follows till the end of the line is ignored. Note that there is no closing symbol. The double slash comment is basically a single line comment. Multiline comments can be written as follows: // This is an example of // C++ program to illustrate // some of its features The C comment symbol...
