Comentarios servir como una especie de documentación en el código. Cuando se inserta en un programa, están efectivamente ignorados por el compilador; ellos están únicamente destinados a ser utilizados como notas de los seres humanos que leen el código fuente. Aunque la documentación específica que no es parte del estándar C + +, existen varias utilidades que los comentarios analizan con diferentes formatos de documentación .

Original:

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.

C + +-estilo
