Computer programming

Computer programming is the process to make code of executable programs  or the process  that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis and generically solving problems resulting in an algorithm correction and its resource implementation of the algorithm in a target programming language, testing, debugging, and maintaining the source code, implementation of the build system. The purpose of programming is making a sequence of instructions that will automate performing a specific task or solve a problem. The programming requires expertise in many different subjects, including knowledge of the application, specialized algorithms, language programming. Source code is written in one or more programming languages such as C++, C#, Java, Python, PHP, Ruby On Real, Dhelpi etc.

The approach to software development may be must have fundamental properties :

Reliability : correction results of a program, its depends of algorithms and minimization of error handling and logic errors.

Robustness : anticipating error programming includes incorrect, inappropriate etc.

Usability : the program is easy  to use, make the user easy to understand, operating the program includes user interfaces etc.

Portability : the range of computer hardware and operating system platforms which the source code or program can be compiled, installed.

Maintainability : the ease which a program can be modified to make improvements or customizations, fix bugs to adapt it to new environments.

Performance : the amount of system resources a program consumes such us processor time, memory space, network bandwidth etc.
