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.

[modifier] C-style
Commentaires de style C. sont généralement utilisés pour commenter gros blocs de texte, cependant, ils peuvent être utilisés pour commenter les lignes simples. Pour insérer un commentaire de style C, encadrez le texte avec
/* et */, ce qui provoquera le contenu du commentaire d'être ignoré par le compilateur. Bien qu'il ne fait pas partie du standard C + +, /** et */ sont souvent utilisées pour indiquer les blocs de documentation, ce qui est légal parce que le deuxième astérisque est simplement considérée comme faisant partie du commentaire. Commentaires de style C. ne peuvent pas être imbriquées .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.
