Keyword, for computer languages, gets defined as a predefined word that gets reserved for working progs that have special meaning and cannot get used anywhere else. Identifier, for computer languages, gets defined as the values used to define different programming items such as variables, integers, structures, unions and others and mostly have an alphabetic character. Catchphrases are preset, saved words utilized as a part of programming that has an extraordinary significance.
Keywords are standard identifiers that have standard predefined significance in C. Such terms get utilized just for their expected reason. A firmly related and regularly conflated thought is a catchphrase which is a word with extraordinary significance in a particular setting.
