- <p>Several object-like macros are predefined; you use them without
- supplying their definitions. They fall into three classes: standard,
- common, and system-specific.
- </p>
- <p>In C++, there is a fourth category, the named operators. They act like
- predefined macros, but you cannot undefine them.
