Declaration Syntax Index

Go Up to Language Structure Index

All six interrelated attributes (storage classes, types, scope, visibility, duration, and linkage) are determined in diverse ways by declarations.

Declarations can be defining declarations (also known as definitions) or referencing declarations (sometimes known as nondefining declarations). A defining declaration, as the name implies, performs both the duties of declaring and defining; the nondefining declarations require a definition to be added somewhere in the program. A referencing declaration introduces one or more identifier names into a program. A definition actually allocates memory to an object and associates an identifier with that object.
