What is Keyword & Variables in C++

18.7k

Keywords are terms that Compiler has already specified as having a certain meaning. These keywords can't be used to identify anything. Keywords are a collection of established identifiers and reserved terms. Predefined identifiers are those that the compiler creates but that the user can change the meaning of.

Variables are storage containers for data values. Distinct types of variables (specified with different keywords) exist in C++. For example, int stores integers (whole numbers) without decimals, such as 123 or -123.

Keywords have a specific meaning that the compiler assigns to them in order to complete a task in code; they cannot be utilized as variables in programming. For example, in C++, there are 64 keywords: for, break, continue, switch, int float, double, char, try, catch, while, and so on.
