各种语言的注释总结--from wiki
Commentscan be classified by: style (inline/block) parse rules (ignored/interpolated/stored in memory) recursivity (nestable/non-nestable) uses (docstrings/throwaway comments/other) Inline comments[edit] Inline comments are generally those that use anewlinecharacter to indicate the end of a comment, and an arbitrarydelimiteror sequence oftokensto indicate the beginning of a comment. Examples: Symbol Languages C Fortran 77and earlier; the 'C' must be in column 1 of a line to indicate a comment. REM,::,: BASIC,COMMAND.COM,cmd.exe, batch files NB. J; from the (historically) common abbreviationNota bene, the Latin for "note well". ⍝ APL; the mnemonic is the glyph (jot overstruck with shoe-down) resembles a desk lamp, and hence "illuminates" the foregoing. # Bourne shelland otherUNIX shells,Cobra,Perl,Python,Ruby,Seed7,Windows PowerShell,PHP,R,Maple % TeX,Prolog,MATLAB,[9]Erlang,S-Lang,Visual Prolog // ActionScript,C (C99),C++,C#,D,Go,Java,JavaScript,Object Pascal(Delphi),Objective-C,PHP,Scala,SASS ' Visual Basic,VBScript,RealBasic !

In this context,whitespaceandnewlinecharacters are not counted as delimiters.
