Comments serve as a sort of in-code documentation. When inserted into a program, they are effectively ignored by the compiler; they are solely intended to be used as notes by the humans that read source code. Although specific documentation is not part of the C++ standard, several utilities exist that parse comments with different documentation formats.

[Bearbeiten] C-Stil
C-Kommentare sind in der Regel verwendet, um große Textblöcke kommentieren, sie können jedoch verwendet werden, um einzelne Zeilen zu kommentieren. Um einen C-style Kommentar einzufügen, einfach Surround-Text mit
/* und */, das bewirkt, dass die Inhalte der Kommentar vom Compiler ignoriert werden. Es ist zwar nicht Teil der C + +-Standard, /** und */ sind oft verwendet, um Dokumentation Blöcke geben, das ist legal, weil der zweite Stern wird einfach als Teil des Kommentars behandelt. C-Kommentare können nicht verschachtelt werden .Original:
C-style comments are usually used to comment large blocks of text, however, they can be used to comment single lines. To insert a C-style comment, simply surround text with
/* and */; this will cause the contents of the comment to be ignored by the compiler. Although it is not part of the C++ standard, /** and */ are often used to indicate documentation blocks; this is legal because the second asterisk is simply treated as part of the comment. C-style comments cannot be nested.The text has been machine-translated via Google Translate.

[Bearbeiten] C + +-Stil
C-Kommentare werden in der Regel verwendet, um einzelne Zeilen kommentieren, jedoch mehrere C + +-Stil Kommentare können zusammen gelegt werden, um mehrzeilige Kommentare zu bilden. C + +-Stil Kommentare sagen, dass der Compiler alle Inhalte zwischen
// und eine neue Linie, die sie sehr nützlich macht ignorieren .Original:
C-style comments are usually used to to comment single lines, however, multiple C++-style comments can be placed together to form multi-line comments. C++-style comments tell the compiler to ignore all content between
// and a new line, which makes them very useful.The text has been machine-translated via Google Translate.
