c99-like fast enumeration syntax (Using the GNU Compiler Collection (GCC)) (original) (raw)

8.9.2 C99-Like Fast Enumeration Syntax

A c99-like declaration syntax is also allowed:

id array = …;

for (id object in array) { /* Do something with 'object' */ }

this is completely equivalent to:

id array = …;

{ id object; for (object in array) { /* Do something with 'object' */ } }

but can save some typing.

Note that the option -std=c99 is not required to allow this syntax in Objective-C.
