Programming or computer programming is the field that deals with the analytical creation of the source codes which are used in configuring computer systems. Computer programmers have the option of choosing either to function in a wide range of programming functions or to specialize in an aspect of development, maintenance or support of computers. Programmers also provide the foundation for the creation and the continuing function of the systems which a lot of people depend upon for different information exchanges, whether for business or entertainment.

Although computer programming primarily concentrates on software design and software development, it also extends to the application of the software for various purposes as well as to the insertion of code which allows for the modification of a program so that it can function properly in a specific environment. It also covers the ongoing maintenance of software which is running as a part of a network. The programmer could work hand in hand with the other information technology specialists as he identifies the issues with the current programs and takes steps in modifying the codes to be able to correct the problem or enhance the overall programm.

Computer programmers make use of languages, which are used to control the way on how computers behave, express algorithms, process information and handle several other tasks and functions. The earliest programming languages are even older that the first computer and were used in controlling the behavior of machines like player pianos and automated looms. More and more computer programming languages are developed every year and range from the simplest to the most complex languages that only advanced programmers use.

One of the more popular computer programming languages would be Visual BASIC, which is an advanced programming language. However, Visual BASIC is considerably easy-to-use and simple to learn. It features codes which is similar to regular written English. It also features a graphical environment for programming since it is visual and events driven at the same time.

Another well-known computer programming language would be Pascal. It was developed by Professor Niklaus Wirth back in 1970. Pascal is considered as an imperative language, or a language which makes use of computations as statements and sequences of commands to change program states. Professor Wirth primarily developed Pascal as a language to be used in filling in the gaps left by the other computer programming languages.

Some other computer programming languages that have been in existence for a couple of decades would be: Fortran, a language which is mainly used for scientific-computing and numerical-based applications such as climate modeling and computational sciences; and C++, which is mainly used for modern computers, as it makes it easier for programmers to write and improve codes.
