NOTE: Strictly speaking, no C dialect
absolutely requires to
|
|
|
declare a
function before it is used. If a call to a previously
|
|
|
undeclared
function is seen, the compiler assumes it is a
|
|
|
|
function
returning int and, in the case of ANSI C/C++, makes
|
|
assumptions about
the types of the actual parameters
|
|
|
appearing in the
call. This serves as an implicit function
|
|
|
|
declaration.
