ISO 646 Alternative operator spellings
This header defines eleven macro constants with alternative spellings for those C++ operators not supported by the ISO646 standard character set:
| macro | operator |
|---|
| and | && |
| and_eq | &= |
| bitand | & |
| bitor | | |
| compl | ~ |
| not | ! |
| not_eq | != |
| or | || |
| or_eq | |= |
| xor | ^ |
| xor_eq | ^= |
In C++, reserved words exist with the same names as these macros and are treated as aliases of their respective operator. Therefore the inclusion of this header has no effect in C++, and is not necessary in order to use the alternative names.
