Introduction
Just like how humans use different languages to communicate with each other, computers and applications have their special languages which humans need to use to communicate with computers and applications. A programming language is a unique language with its vocabulary and grammatical rules, that humans can use to instruct a computer or an application to perform desired tasks and activities. The process of computer programming is the process of writing code/instruction in specific programming languages to facilitate a computer or computer device to carry out specific activities or tasks. There are various programming languages such as Java, Python, C, Ruby, PHP, SQL, etc. From this article, you will get to know Most Used Programming Language.
Computer programmers are individuals who specialize in and learn these different programming languages. Their fluency in these languages determines their skills and competency. There is a rising demand for computer programmers in the world due to the automation of various day-to-day tasks.
Due to this rising demand, many people, especially youngsters who are passionate about technology, are enrolling themselves in courses to learn programming languages. Many websites and platforms are offeringcomputer programming courses, through which one can become an expert in one or more programming languages of their choice.
