Programming Languages
Definition of the term “program”
A program in computing is a predefined list of instructions that, when run or 'executed ', tell a computer to carry out a task and how to it.
Overview of procedural, object orientated and event driven programs
In programming, there are many different paradigms, also known as structures or styles that allow the programmer a means to build or structure different elements within a computer program. These paradigms are: procedural, event driven and object orientated.
Applications that can be developed using these paradigms
Procedural programming uses a list of instructions to tell the computer what to do step-by-step. Procedural programming relies on - you guessed it - procedures, also known as routines or subroutines. A procedure contains a series of computational steps to be carried out. Procedural programming is also referred to as imperative programming. Procedural programming languages are also known as top-down languages.
Procedural programming is intuitive in the sense that it is very similar to how you would expect a program to work. If you want a computer to do something, you should provide step-by-step instructions on how to do it. It is, therefore, no surprise that most of the early programming languages are all procedural.
The procedural paradigm uses a list of instructions as a basis. These tell the computer what to do, and how to do it step by step. The procedural paradigm does rely on subroutines or
First let us take a look at computer programming. This element takes on different program designs created by engineers and uses one of several different programming languages to write executable code that computers can read. Programming is the source for
In order for IT System to become active first Computer Programs and Programming must be put in place. Computer Programs and Programming are simple terms an executable set of commands for the computer to perform. A process is an actively running program which may or may not is running in the background. A program running in the background is one that the computer user may not be aware of, but it may be providing useful services such as an ability to connect to other computers. It reads and executes program instructions, performs calculations, and makes decisions (slideshare.net).
This paper will discuss the difference between procedural modules and object-oriented methods. How both methods work and some of the pro
Machine code it the language that the computer understands. High level languages are better because they are easier to understand and work with.
Algorithms are set of steps for solving a problem; algorithms also make the program faster. For example, when you are checkers games and you want the user to be able to play against the computer. Computer scientist must figure how to a checkers’ program that never loses by using the minimax search algorithm to search through the huge tree of possible moves. Another interesting topic that I learned in the video is object code. Object code is the output of a compiler after processes source code; source code was written by a human in a programming language for a computer program. A compiler is a conversion of source code into object code. Object code is usually a CPU, but sometimes it designed to convert source code into an assembly language or into some other programming

In order to solve the programming problem that we are facing, we need to define the flow of the program and the actions that the program must take. Attempting to write a successful program without considering how to solve the problem and how the program must be created makes the task very difficult for the programmer. This is where flowcharts or pseudocode will help us build a conceptual model of how a program will work before we get into the complexity of the programming language.
An Event Driven Program is not restrained by the style of procedural programs, instead of the top to bottom functionality of a procedural program, where the code starts at the top and just reads down, on an already determined path, instead of this, event driven programming has code placed in logical areas of events, this code is not used in a determined order as the user has full control over the program by triggering
Now, we will look into what Object Oriented Programming is. Before that we must first understand what an object is, because that is what the entire programming method is based on. An object is something which has a defined state and characteristics of its own. This concept was taken from the real world scenario, where each object we see has those two states. An example would be a cup, it has a height, it has a purpose and it has a specific volume which it can hold. The shape of the cup can also be taken into consideration. In software programming, the object is worked upon by use of methods. The methods are what help two or multiple objects communicate with each other (“Object Oriented Programming”). Thus we can now say, Object oriented programming works on “objects” instead of working directly on the actions as in case of Procedural programming. Although, indirectly we are working on their actions because that is what makes the entire program work. Objects once defined can be used infinite times in a program and we do not have to define them. Thus, object oriented programming focusses more on getting the logic of the program right instead of spending several lines of code trying to get the data definitions right. The most commonly used Object oriented programming languages are Java, C#, PHP and Visual basic designed for .NET framework. An example of PHP object oriented programming would help us understand the actual programming
Programming languages are vast and diverse in their numbers. These different languages use fundamental styles of programming called programming paradigms. These programming paradigms layout the particular design approach that a program will use to solve a problem or achieve an objective. Of the many different types of programming paradigms, some of the more distinguished ones are procedural, functional, logical, and object orientated programming. Recently the object orientated languages have been rising in popularity due to their ability to easily implement large programs. There are many different object orientated programming languages (OOPLs), among them are C#, Java, Ruby, and Python. This essay will compare and contrast two of these languages: Python and Java.
A programming language is an artificial language which gives instruction that is carried out by a computer. The researcher chose this project to understand and learn about Programming language design, structure and computer software development. The researcher wanted to find out how object oriented programing languages work, their processing, how they are designed to complete tasks and how they affect the software development. In his investigation, he researched the basic common qualities of an object oriented programs
A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.
What is an algorithm? According to the textbook, an algorithm is a set of specific sequential steps that describe exactly what the computer program must do to complete the required work. Figure 10.4, on page 426, shows the stages that each programming project follows. Step two is where the algorithm is, which is “making the plan.” The example the book uses is the pharmaceutical companies designing new drugs. When they design new drugs, they have to use complex computer programs that model molecules. The computer software programs help chemists create the new drug in a quicker manner that give the desired pharmacological effects.
A procedural programming a program that contains a series of computational steps to be carried out. Procedural programming is a term to denote the way in which a computer programmer writes a program. This program works by using sequences of instructions. The types of procedural programming are pascal, c++ and c.
