Lesson 5 - Computer Programming

Computer programming is defined as process of writing a set of instructions called program that direct the computer to perform a specific task. The set of instructions are written in programing language that computer can decode and execute.

The computer programing continues to be the most popular choice for students opting a career in computer science. Learning computer science is now considered to be of the best option.

The computer programing expertise can get your dream job with top notch technology company as a software developer with excellent financial rewards. The computer programming skills can put your career on the fast track.


Computer Programs

A computer program is a group of instruction written in any programming language depending upon the purpose and type of the software being developed.

The computer programs are written to perform a specific task. For example, a computer program to play music in your computer or to play game and so on.

Each computer program usually consist of number of program statements. Each program statement performs a part of the job.

The programmer must write the program statements as the programming language syntax



 Programming Languages

A programming language is a vocabulary and set of grammatical rules for instructing a computer to perform specific tasks. Computers can only understand special machine languages, which consist almost entirely of numbers. Humans, however, can’t understand these huge series of numbers, so they use high-level programming languages, such as C++ and Java to write software programs and then translate or compile them into machine language. Every language has its strengths and weaknesses. For example, FORTRAN is a good language for processing numbers, but it’s not well suited to for large programs. C++ has powerful object-oriented features, but it is complex and difficult to learn. There are literally hundreds, if not thousands, of programming languages out there.

The programing language are generally classified as high and low level language. The higher level programming languages are more human readable and the lower level programming languages are more machine readable.
