All about Computer Programming Career

Computer programming is one of the most important and exciting careers today.  It is also a field that offers plenty of job opportunities for graduates.  It’s one of the best fields of endeavor for people who love technology and are willing to try out new things.  If you’re considering pursuing a computer programming career, here are some things that you should know:

What is computer programming?

Computer programming is basically the process of writing codes to create a computer program.  A programming language is used to write this code, also known as the source code.  Computer programming is actually an umbrella term that encompasses all types of programming involving the use of computers.  The design and method utilized to write a source code will depend on the type of computer language used for the job.  Some of the most common computer languages include BASIC, COBOL, FORTRAN, C++, Java, Visual Basic, Python and PHP.

The job of computer programming also includes testing the source code, debugging it to check for flaws and weaknesses and maintaining it to ensure optimum performance.

Creating the code

The soul of computer programming is the creation of the source code, which can either be brand new or something created to modify or improve upon an already existing code.  The object of the source code is to build a program that will perform a particular series of tasks based on a specific set of commands.  This is called customization.

The end result of writing the source code is a computer program.  In software engineering, computer programming is an important initial phase.

What does a computer programmer do?

The main job of a computer programmer is to write the codes that serve as the foundation of software programs.  He is also tasked to test, troubleshoot, debug and maintain the program to ensure its quality and reliability.

Generally, the tasks that a computer programmer must perform are assigned by another person, usually the system analyst.  The computer programmer’s job is then to write the program, test it, modify it if necessary and ensure that it passes compatibility and quality standards.  If errors are found, it is the computer programmer’s job to ensure that they are corrected.

The job of a computer programmer usually requires hours upon hours spent in front of a computer to design and write a computer program.  Depending on the type of program being written, its purpose and the complexity of the commands required in order for a computer to execute the series of steps involved, writing a program can take several months to several years to complete.

The length of time it often takes for a program to be completed often necessitates having a single program broken down into a smaller series of steps.  These steps will then be assigned as tasks to a group of programmers who will work on them independently.  The final step is to put the end results and produce one coherent and useful computer program.

Computer programming is a very dynamic field and involves plenty of imagination and discipline.  Although there are set standards for the tasks involved, the profession itself does not require certification tests from government agencies.  There are also no state and federal licenses to obtain.

How much does a computer programming job pay?

That will depend on the experience and level of expertise of the programmer.  Most entry level programmers earn a minimum of about $33,000 a year while mid-level programmers earn approximately $50,000 a year.  For senior level programmers and those who have several years of experience behind them, their typical take-home pay averages at about $65,000 a year.  Consultants, some managers and those who have advanced well in their computer programming career are often paid more.

Computer Programming Functions

When it comes to computer programming vocabulary, there are so many terminologies that people who do not have enough know-how tend to become lost and confused.  One term could be translated into so many different names in different languages.  For example, the following words are quite similar: Functions, Programs, Subroutines, Procedures, Subprograms, or Sub queries.  The only question now is which of these terms could stand on their own.

Theoretically speaking, computer programming avoids the duplication of any code in multiple spaces.  For example, one institution utilizing the programs could have some libraries of different thousands or even more programs with billions of basic code lines.  With such intricate case, duplication could still be avoided.  Let us say that an error message occurs because the collection now needs to have an additional ‘member’.

A good example is the addition of another global currency called the Euro.  If each and every program will be told to update itself because of this new addition, it could be complex.  But with sub-programs or functions specifically designed to handle diverse situations, then the only function that would take care of the change would be the one assigned to handle such a scenario.

In the same way that we write new programs, many of the components that it will need are already in existence (e.g. accessing a certain file to dig up a certain data, computing inventories on hand).  In cases such as this, a good alternative to writing different source code lines to work on the new function (and eventually replication of the code onto numerous other programs), the sub-program is accessed to work on the specified function.

In a handful of programming languages, there are certain parameters that are being passed from a specific program name to the program that is being called to do a task.  A secondary program usually makes the values altered and then the control is brought back to the main program.  These actions could be levels deeper.  The various programs that are being used to call each other are written in so many varying languages.  The reasons behind this are:   to have a reasonable controllable function pieces and having various languages means being better able to suit different function types.

Types of functions in Computer Programming

To further define the uses of programming functions, a function may appear in two different locations or even a single location.  This depends on whether it is multi-line or single-line function.  A function that is single line is one that gives back a value after performing tasks (all of this in a single line).  The multi-line function, however, is stretched on many different lines.

A single line function could show in a code block all because it only responds when called by a certain name.  The multi-line function does otherwise.  If it is a multi-line function that is being defined in a block of code, then the statements that follow the definition are done in a non-sequential manner.

In its simplicity, functions are code blocks that can be reusable.  These code blocks often return single values (sometimes they don’t’).  Common examples of these code blocks are Mathematical functions (e.g. tan or log), date functions (figures between two dates), or string functions (looking for incidents of 1 string located within another string).  Functions are also kept separately from the primary program code.  A lot of programming language has specific functions which are delegated as entry points to a certain program.

Knowing what functions are in computer programming could take sometime to non-computer savvy individuals.  But the basics are all here.  Looking at the many complex things that functions do, you get to appreciate the things that the computer does for you each day, don’t you?

Computer Game Programming

All about Computer Game Programming : Many people will play computer games without any knowledge of how much work went into the game. True, a lot of thought and creativity had to be employed in order to make the game work, but the game also required a good deal of computer programming and knowledge of different computer programming languages in order to make the game not only feel real, but look attractive as well. There are many sides of computer game programming, so if you are interested in computer game programming and may want to take up courses in the future, take a look at this list.

The game physics programmer is someone who directs how a game uses physics in order to look correct and feel correct. In most cases, a computer game will not completely simulate the physics of a real world, but some important aspects of physics may have to come into play for some games. For instance, wind resistance might be important to dogfights, while the fluid but retarded movements of some characters in water might be needed for a role-playing game.

The artificial intelligence programmer is the one in charge of developing the logical sequence of the game itself. For instance, when a game involves finding a path, employing strategies, or giving rise to enemy tactics, an artificial intelligence programmer may be called in to make a game smart – in other words, to make the game think on its own. In general, the computer language used for artificial intelligence programming is simpler than other languages, and it can be shared with the game’s players.

The graphics programmer uses a series of codes and algorithms in order to provide graphics in the world of the game. In the modern age, a graphics programmer has to work in a three-dimensional environment, and should therefore have knowledge of calculus, vector math, and other algebra concepts that may be needed for specializing in rendering such images. There are only very few graphics programmers, and they may usually demand high wages for their work.

A sound programmer will provide sounds in terms of characters’ dialogues, music, and even sounds that can make the game seem more real, such as the sound of crunching leaves or grass as characters walk on them. The game play programmer will add to the experience of the game, and will do so by focusing on the game’s feel and strategy.

Computer game programming will also require a team of scripters, who are also usually the designers of the game. These scripters write the code of the game itself, usually with a basic computer language. Also needed are user interface programmers, or the UI: the UI programmers will create a library of different aspects that can be used across a wide variety of worlds within the game, or a wide variety of games within a manufacturer. The UI programming language involves a good deal of math, with the aim of producing special effects.

Also important is an input programmer, who writes codes for how different kinds of hardware, such as the keyboard, joystick, or mouse, will affect the game. The network programmer will find ways for the game to work on a network, where people can play against each other. A porting programmer ensures that the game can work on different platforms and operating systems.

Overseeing all these tasks is the lead game programmer. These are only a few aspects of computer game programming. As the field widens, more and more programmers of different kinds will have to be called in and identified as important.

Basic Programming Language

All about BASIC Programming Language – Computer programming has its own language, and that’s just the beginning of the software adventure. There are many different languages in computer programming, and all of them have their own purposes. In order to understand the importance of computer programming languages, knowing them, and tweaking them, one has to understand the importance of computer programming. Computer programming produces software packages, among other things, to meet our needs. We may need software for accounting, making photos bigger or smaller, or editing our home videos. Behind all these software packages are the computer programmers who use their individual languages in order to create the software.

One such computer programming language is the Beginner’s All-Purpose Symbolic Instruction Code, or BASIC. BASIC is actually composed of many different kinds of programming languages that are actually higher level than most other languages. This BASIC family of computer programming languages was first designed in the 1960’s, and was originally made for non-science people to gain better access to computers. During that time, using a computer required that a person write customized software, a task that only mathematicians and scientists were equipped to do. The BASIC language was therefore a bridge for people of other professions to take advantage of the power of computers.

When the 1970’s came, the BASIC language, whether in its original form or a variant of it, spread onto microcomputers; and by the 1980’s, even home computers could be run in BASIC. Today, BASIC remains popular, as it serves as the basis for many of the more modern programming languages that have been developed in the wake of advanced operating systems and the Internet.

When it was originally conceived, BASIC was meant for beginners: it was a language that people could use easily, whether or not they were educated in mathematics and the sciences. The language also had to be a general purpose one, in that it had to serve many different needs, and not only those that mathematicians and scientists required. The root language of BASIC also had to allow for advanced features to be plugged on as experts grew more and more adept in it, and as the language found further use in many other fields. BASIC was also meant to be interactive, and was designed to show error messages that were clear and friendly; that is, these error messages had to completely explain what the problem was, which would hopefully allow the user to fix it faster and easier.

When it was first released, moreover, BASIC was free of charge, which allowed the language to spread much faster. Once the language spread much faster, it was also easy to modify it and correct errors. BASIC was also distributed to a few high schools in order to promote it faster. Thanks to this widespread use of the language, BASIC was soon implemented on several microcomputers, and by several software manufacturers.

Despite its success, BASIC has had its dissenters. For instance, some programmers find that its scripts do not show proper programming practices, and the language itself is too slow, or sometimes even too simple. Despite all these, however, BASIC has continued to thrive, succeed, and evolve, and has thus become a good tool to introduce beginner programmers to the concept of coding and computer programming.

These are only a few facts about the BASIC language. For more information on BASIC, read and do your own research through several key pages online, or using computer programming books.
