3.7 Predefined Macros

Several object-like macros are predefined; you use them without supplying their definitions. They fall into three classes: standard, common, and system-specific.

In C++, there is a fourth category, the named operators. They act like predefined macros, but you cannot undefine them.

3.7.1 Standard Predefined Macros  
3.7.2 Common Predefined Macros  
3.7.3 System-specific Predefined Macros  
3.7.4 C++ Named Operators
