Function prototype

Function prototype is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Some languages provide the facility to declare functions and subroutines through the use of *function prototyping*. The task is to demostrate the methods available for declaring prototypes within the language. The task should include:

• An explanation of any placement restrictions for prototype declarations
• An example of a prototype definition for a function that does not require arguments
• An example of a prototype definition for a function that requires two arguments
• An example of a prototype definition for a function that utilizes varargs
• An example of a prototype definition for a function that utilizes named parameters
• An example of prototype definitions for subroutines or procedures (if these differ from functions)
• An explantion and example of any special forms of prototyping not covered by the above
