In C, C++, C# and other programming languages, an identifier is a name that is assigned by the user for a program element such as variable, type, template, class, function or namespace. It is usually limited to letters, digits and underscores.
The #define directive causes the compiler to substitute token-string for each occurrence of identifier in the source file. The identifier is replaced only when it forms a token. That is, identifier is not replaced if it appears in a comment, in a string, or as part of a longer identifier.
