Contents|Index|Previous|Next The #else directive   The #else directive can be added to a conditional to provide alternative text to be used if the condition is false. The following example shows what it resembles. #if expression  text-if-true  #else /* Not expression */ text-if-false #endif /* Not expression */ If expression is nonzero, and thus the text-if-true is active, then #else acts like a failing conditional and the text-if-false is ignored. Contrarily, if the #if conditional fails, the text-if-false is considered included. Top|Contents|Index|Previous|Next
