identifiersare the unique names assigned to variables, functions, classes, structs, or other entities within the program. For example, in the below statement, int num = 11; numis an identifier. Rules to Name of an Identifier in C++ We can use any word as an identifier as long as it follows the following rules: An identifier can consist ofletters(A-Z or a-z),digits(0-9), andunderscores (_). Special characters and spaces are not allowed. An identifier can only begin with aletter or an underscore only. C++ has reservedkeywordsthat cannot be used as identifiers since they have predefined meanings in the language. For example,intcannot be used as an identifier as it has already some predefined meaning in C++. Attempting to use these as identifiers will result in a compilation error. Identifier must beuniquein its namespace. read less
