Language Summary

Objective-C adds a small number of constructs to the C language and defines a handful of conventions for effectively interacting with the runtime system. This appendix lists all the additions to the language but doesn’t go into great detail. For more information, see “The Language.” For a more formal presentation of Objective-C syntax, see “Grammar.”
