Unit 6P1


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.
