C – What does “C” stand for?

The most usual meanings of the abbreviation “C” are probably: Celsius/Centigrade to indicate the temperature. We say “Degree(s) Centigrade, or Degree(s) Celsius, where “C” (noun) is a degree on the so-called centigrade scale of temperature. “C” is also frequently used as the symbol to indicate the speed of light in a vacuum (299,792,458 meters/second).

Furthermore, “C” is a general-purpose and high-level computer programming language. This language is perfect to develop firmware and portable applications. The computer language C was initially developed in the 1970s by Dennis Ritchie at Bell Laboratories for the company’s Unix Operating System and was initially developed for writing software systems.

C is one of the world’s most widely applied computer languages and is compatible with the most-used computer systems. C has had a great influence on many contemporary computer languages, notably C++.

The language C is part of the procedural, structured paradigms of computer languages. It is flexible, powerful, and proven and can be used for a host of different applications. C is relatively high-level but it shares many attributes with assembly languages.

So you see, one simple letter, C, can have many different meanings, depending on the environment in which it is used. But as always, there are so many more meanings and applications. Just about every jargon has its own use of C and within that professional or social field, people will understand how to use it correctly. Here we go:
