C + + (und C) Quellcode kann in jedem Nicht-ASCII-7-Bit-Zeichensatz, der ISO 646/ECMA-6 invarianten Zeichensatz enthält geschrieben werden. Jedoch mehrere C + + Betreiber und Interpunktionszeichen erfordern Zeichen, die außerhalb des ISO 646 Codesatz sind: {, }, [, ], #, \, ^, |, ~. Um Zeichenkodierungen denen einige oder alle dieser Symbole nicht existieren verwenden, C + + definiert zwei Arten von Alternativen: zusätzliche Schlüsselwörter, die den Betreibern, die diese Zeichen und spezielle Kombinationen von zwei oder drei ISO 646 kompatible Zeichen interpretiert werden, verwenden entsprechen als wären sie eine einzige nicht-ISO 646 Zeichensatz .
Original:
C++ (and C) source code may be written in any non-ASCII 7-bit character set that includes the ISO 646/ECMA-6 invariant character set. However, several C++ operators and punctuators require characters that are outside of the ISO 646 codeset: {, }, [, ], #, \, ^, |, ~. To be able to use character encodings where some or all of these symbols do not exist, C++ defines two kinds of alternatives: additional keywords that correspond to the operators that use these characters and special combinations of two or three ISO 646 compatible characters that are interpreted as if they were a single non-ISO 646 character.

Primary Alternative
&& and
&= and_eq
& bitand
| bitor
~ compl
! not
!= not_eq
|| or
|= or_eq
^ xor

[Bearbeiten] Kompatibilität mit C

Die gleichen Wörter werden in der Programmiersprache C in der Include-Datei <iso646.h> als Makros definiert. Da in C + + sind Schlüsselwörter der Sprache, die C + +-Version von <iso646.h> sowie <ciso646>, definiert nicht alles .
Original:
The same words are defined in the C programming language in the include file <iso646.h> as macros. Because in C++ these are language keywords, the C++ version of <iso646.h>, as well as <ciso646>, does not define anything.
