P1 - describe the application limits of procedural,
object oriented and event driven programming paradigms
Procedural
Programming language
Procedural programming languages are used to solve a lot
of different problems.
This style of programming was brought as a
result of lines of code being too complex and time confusingly long; thousands
of lines of code were needed for one program. The procedural approach of
programming was brought in so that users would break down these lines of code
into block of around 10 lines of code; these blocks were used to carry out
specific actions for the final release of programs. These are procedures
acquiring to the name of this style of programming it is called Procedural
Programming. In procedural programming a program would be built by writing
these functions/procedures and calling upon them when you need them to perform
a function within the program.
Object
Oriented Languages
Object – orientated programming (OOP) – OPP takes a
different approach to the stricture of a complex program. OPP was developed in
a format to help with the difficulties that were troubling in the creation of
highly complex system using the procedural approach. With OPP, a program is
broken down into objects rather than procedures.
Event
Driven Programming
The first programming language limitations that I will
discuss will be EDP language. This language will be hard to get to grips with because
it is complicating; also it is only really easy to use with a GUI, graphical
user interface, and framework such as frames per second (FPS). If you made a
program with a calculation using a few textboxes and a button you will only get
those values calculated once the button is clicked. This is fine but where the
limitation stands if you wanted to get rid of the GUI you would need to recode
all over again as the previous code would be bases on a GUI system and wouldn’t
be able to be put somewhere else.
Object
Oriented Programming
OOP will be the second language that I will look at; some
of the limitations for this programming language are that a lot of tasks must
be done manually; they are difficult to modify or extend within an application
that has been made.
Procedural
programming
Procedural programming is extremely advanced in
performance, however like everything it does have limitations; one of the more
serious limits is “spaghetti-code”. Spaghetti code is a form of code that would
have had to have been written too many times so that the flow will become
unusable to new programming coming onto the project. The new programmer will
then have to take a preoperational-course which will enable to begin to
understand the software. This is caused because the code will constantly have
to be changed and adapted in order to meet the user demand which means
introducing things like sub loops and new methods altogether is a hard to
adapt. However there is no good tool which is for abstraction, which is
something that only exists as an idea, and modularization in procedural languages.
This means that it’s hard to add new functionality or change the work flow
without going back and modifying all other parts of the program.
List
of six programming languages most commonly used:
PHP-PHP
is an open source web development language through HTML and supports cross
platforms.
C#-C#
is a general object orientated programming source this was developed by Microsoft
as part of .NET.
JavaScript-JavaScript
is not Java sounds confusing now doesn’t it but really its simple JavaScript is
an object orientated scripting program. Also this program is easier to code and
is smaller than Java itself.
VB.NET (Visual Basic.NET)-VB.NET is an object orientated implemented
program designed by Microsoft’s.NET framework and is a lot easier to use than
other scripting programs.
Python-Python is basically
python would be classed as object orientated but is open source language based
program it also utilizes memory management.
Java-Java
is an object orientated based program developed by James Gosling
in Sun Microsystems in the early 1990s. Developers describe this programming
language to be “beautiful” because it is not part of the .NET framework or
developed by Microsoft.
Why are there so many languages?
There are so many languages
simply because new languages are designed and built to update existing
languages such as C-C++ making improvements for a better user experience also
there are so many languages because some languages are specially designed to do
certain jobs or to create light weight applications Java is a good example to
use for light weight applications.
