Computer Programming Basics

Individuals who want to learn computer programming and the languages that can be used in making programs must first be familiar with the basics. Languages employed in programming should be one of your primary considerations. Prior to creating programs, it is crucial that you know the different types and levels of programming languages. Among these are:

1. Machine Level Language
We all know that computers work in bits and bytes and it reads and understands binary digits 0 and 1. While you are free to make a program in any language you want, it has to be transformed into the languages of Os and 1s before it can be implemented.

It means you need to write a program or to convert your written program into machine language. And this is no easy task. It is nearly impossible to memorize a long sequence of 0s and 1s for each instruction you wish to be executed.

Yes it is true that before the development of high level languages, the ones used in making programming codes are machine level languages. These days, however, this level of language is not used anymore in designing computer programs.

2. Assembly Level Language
This level of programming is only one level higher than low level or machine languages. This is actually the reason why creating a program using such languages isn’t a piece of cake, although, the programming code produced is pretty understandable.

Until now, there are lots of programs for embedded technology that are created in assembly language. The program that’s responsible in transforming assembly level programs into machine level programs is called the assembler.

3. High Level Language
These computer languages are easier for humans to understand. It entails clear statements for making each instruction. Languages that fall in this category have different purposes. There are languages designed for web programming; some for desktop applications, while others can perform both tasks.

One thing to bear in mind though, high level language isn’t easy for the computer to understand. This is where the importance of an interpreter or a compiler comes in. Such programs transform the programming code into a language form the machine can understand.

Aside from these three basic levels of languages, another generation of programming language is now being designed. This is dubbed as the fourth generation language which is designed for those who have very minimal or no programming experience.

Developers of such language want these inexperienced programmers to learn to prepare their own code. This is also the very reason why high level languages like Java already came with these systems. These enable a person to write a programming code without memorizing every function.

Bear in mind that no matter what programming language you want to learn, you need to have proper understanding of the basics. If you’re not familiar with programming language basics, you will not be able to make a program in that specific language. It is advisable that you take up computer courses so you’ll be able to learn more than just the basics of computer programming.

Computer Programming For Beginners

Are you new in the field of computer programming? Then it is very important to know and understand the common concepts and principles involved in such field. While computer programming for beginners comes with a certain level of difficulty, it is still achievable especially if you are equipped with the basic principles and concepts.

Writing a program involves storing data as well as manipulating it by means of a series of instructions. Included in the data are time and countable factors such as names, dates, and descriptions. By means of data types, you’ll be able to find out how a data must be stored and used.

Most programming languages such as C, C#, C , Visual Basic, and Java have integral parts which novice programmers need to get acquainted with. Among such parts are:

  • Variables

Wannabe programmers have to understand that variables provide them with momentary storeroom for any information needed while the program is used. Variables also play a great role in moving information from one section of the program to another. There’s also the so-called local variable which can be accessed or modified by a specified portion of a program and global variables which are accessible to any part of the program.

  • Data types

Any computer language comes with data types because they help maintain information contained in the program. However, programming languages have some restrictions on the data types they provide. Among the popular data types are characters, pointers, numbers, and strings. Numbers come in either floating points or integers. String data conceals internals that can be manipulated via exposed functions. Additionally, character data type stocks up numbers, symbols, letters, and spaces while the pointer means a piece of memory which can also be utilized for storing arrays.

  • Output

Since it is an important part of any programming language, it is advisable that you have a good understanding of the various types of outputs in majority of the computer programming languages. One of the popular types is text output, which provides a simple means of revealing the result of a particular computer program. Graphical output is a bit difficult and it needs higher resolution.

  • Testing conditions

These allow you to find out the path through a program by implementing a code with value as the basis. This value, which can be variable, another expression, or constant, is compared against an expression. One example of a testing condition statement is “if”. In case the validations became unsuccessful, many computer languages let you define a chunk of code that needs to be executed using “else” statement.

Aside from the indispensable elements of programming languages, computer programming for beginners also requires you to be familiar of the different language categories which include compiled languages, mark-up languages, and programming languages. It is also wise to have full understanding of the general principles and concepts behind each and every programming language. All of these factors are very much useful in helping you become an expert in a particular programming language or in computer programming in general.

Introduction to Computer Programming

Since computer science was recognized as a distinct academic field in 1960s, it has made great strides especially in making things a lot easier for humans. One of the issues it has solved is the way problems that need to be addressed have been translated into a code or format computers can understand. There are various ingenious and great solutions used in such problems. Here’s an introduction to computer programming that will give you a greater understanding of this exciting discipline.

In order to pass on instructions to computers, programming languages are used. These languages, which are designed by humans, are based on the so-called rules of syntax and semantics. These days, a wide range of languages have been made, employed, discarded.

Programming languages usually don’t last that long. They come up but after just a few years of stay in the industry, you will feel that the language needs some improvement or you need something your chosen language can’t provide. It won’t be long until that particular language is replaced by a more flexible successor.

Programming languages do evolve because there’s a continuous search for efficient transformation of human language into machine code. Languages produced usually start with ideas, which conceal hardware and employ representations that are more convenient to human programmers. Another crucial facet of language design is dealing with the program’s complexity. As programs become bigger and more refined, developers have come to realize that there are language types that are easier to support in huge systems. Because of this, event-driven and object-oriented languages became widely used.

Types of Programming Languages: An Overview

Since this field is evolving, there is no set standard in categorizing programming languages. One way to characterize them is through programming paradigm. These classifications include:

o Object-Oriented

Object-oriented programming isn’t just the newest; it is also the most powerful among the paradigms. In programs that are object-oriented, the designer indicates the data structures as well as the categories of operations that can be done on it. The combination of data and operations that can be carried out is dubbed as an object.

o Procedural

Procedural programming involves a list of actions a program needs to accomplish to be able to attain certain goal. This is a simple paradigm wherein a program is divided into a starting phase, list of operations that needs to be done, and ending stage. Also called imperative programming, procedural programming involves the idea of procedure call.

o Structured

A unique type of procedural programming, structured programming offers additional tools that can be used to deal with the issues produced by larger programs. In structured programming, the program is split into small codes that can easily be understood. Oftentimes, structured programming is associated with top-down approach which starts with an overview of the system.

Computer programming languages are artificial and are made to manage computers. To come up with new and better language, the developer needs to spend hard work and long working hours. With this introduction to computer programming, you’ve become familiar with the various types of languages based on paradigms.

Computer Programming A Career

Computer programming training is considered by most employment forecasters to be one of the best educational tracks with regards to career outlook in the future. An education in computer programming, whether through a traditional college degree program or a certification class, can open up many doors for job-seekers looking to secure employment in this rapidly changing field.

What is Computer Programming?

The science of programming – and it IS a science – involves developing and inputting the set of instructions that computers use to function, as well as resolving problems and conducting logical tests within the system. Every company utilizes some type of computer system these days, and although the role of the computer programmer is largely dependent on the type of company that he/she works for, the position is always a professional one due to the enormous amount of responsibility.

“Computer programming and robotics”

Over the years, computer programming has changed drastically as technology evolves, and computer programmers have been at the very forefront of that change. In essence, computer programmers are charged with instructing computers how to think by inputting a series of algorithms and other data, and making changes to those formulas when problems arise.

What Are the Requirements for Computer Programming?

Different types of programming require varying levels of time and expertise. Simple programs can usually be written within a matter of hours, while more complex programs can take years to complete. Either way, the computer programmer must be proficient in the language of programming and be able to resolve problems “on the fly” using logical thinking and sequencing.

According to one of the more popular career sites, most computer programming positions require at least a Bachelor of Science in a computer-related field, but there are some professional programmers who have learned and perfected their skills through work-related experience only, instead of a formal degree program. Regardless of entry-level educational requirements, however, most programmers find they need to consistently seek out new training and certification opportunities in order to stay abreast of the current technology.
