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.
An identifier defined as empty text is considered defined. The defined directive can be used in an #if and an #elif directive, but nowhere else. The function call to credit is compiled if the identifier CREDIT is defined. If the identifier DEBIT is defined, the function call to debit is compiled. If neither identifier is defined, the call to printerror is compiled.
