What Is Programming?

Programming 

It is the process of creating a set of instructions that tell a computer how to perform a task. Programming can be done using a variety of computer "languages," such as C/C++, Java, Python, Ruby, Swift, Kotlin, SQL and many more.

If you had never learned to programme earlier then you might be wondering what is programming? So, basically, when we write a program, we're giving the computer a series of commands that kind of look like a weird form of English.

Computer programming is the process of designing and building an executable computer program for accomplishing a specific computing task. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms in a chosen programming language (commonly referred to as coding).

Programs are behind the websites and the apps that you use every day, all the time, like Google Maps, and Wikipedia, and YouTube.

Quality Requirement

Whatever the approach to development may be, the final program must satisfy some fundamental properties. The following properties are among the most important:

• Reliability: how often the results of a program are correct. This depends on conceptual correctness of algorithms, and minimization of programming mistakes, such as mistakes in resource management (e.g., buffer overflows and race conditions) and logic errors (such as division by zero or off-by-one errors).

• Robustness: how well a program anticipates problems due to errors (not bugs). This includes situations such as incorrect, inappropriate or corrupt data, unavailability of needed resources such as memory, operating system services and network connections, user error, and unexpected power outages.

• Usability: the ergonomics of a program: the ease with which a person can use the program for its intended purpose or in some cases even unanticipated purposes. Such issues can make or break its success even regardless of other issues. This involves a wide range of textual, graphical and sometimes hardware elements that improve the clarity, intuitiveness, cohesiveness and completeness of a program's user interface.

• Portability: the range of computer hardware and operating system platforms on which the source code of a program can be compiled/interpreted and run. This depends on differences in the programming facilities provided by the different platforms, including hardware and operating system resources, expected behaviour of the hardware and operating system, and availability of platform-specific compilers (and sometimes libraries) for the language of the source code.

• Maintainability: the ease with which a program can be modified by its present or future developers to make improvements or customizations, fix bugs and security holes, or adapt it to new environments. Good practices during initial development make the difference in this regard. This quality may not be directly apparent to the end user but it can significantly affect the fate of a program over the long term.

• Efficiency/performance: Measure of system resources a program consumes (processor time, memory space, slow devices such as disks, network bandwidth and to some extent even user interaction): the less, the better. This also includes careful management of resources, for example cleaning up temporary files and eliminating memory leaks.
