A prologue comment is a comment (or group of related comments) located near the top of an associated programming topic, such as before a symbol declaration or at the top of a file. An inline comment is a comment that is located on the same line as and to the right of program code to which is refers. [ 8 ]
All examples are given for languages with C-like comments where a multi-line comment starts with /* and a single line comment starts with //. Doxygen ignores a comment unless it is marked specially. For a multi-line comment, the comment must start with /** or /*!. A markup tag is prefixed with a backslash (\) or an at-sign (@). [16]
Python has two ways to annotate Python code. One is by using comments to indicate what some part of the code does. Single-line comments begin with the hash character ( # ) and continue until the end of the line.
Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP. PHP supports standard C/C++ style comments, but supports Perl style as well. Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19]
However, they are still useful for command-line interfaces and plaintext comments within source code. Some recent embedded systems also use proprietary character sets, usually extensions to ISO 8859 character sets, which include box-drawing characters or other special symbols.
Many languages have a syntax specifically intended for strings with multiple lines. In some of these languages, this syntax is a here document or "heredoc": A token representing the string is put in the middle of a line of code, but the code continues after the starting token and the string's content doesn't appear until the next line. In other ...
#lang racket (displayln #<<A here string in Racket ☺ This string spans for multiple lines and can contain any Unicode symbol. So things like λ, ☠, α, β, are all fine. In the next line comes the terminator. It can contain any Unicode symbol as well, even spaces and smileys! A here string in Racket ☺)
Each symbol type is represented by a single character. For example, symbol table entries representing initialized data are denoted by the character "d" and symbol table entries for functions have the symbol type "t" (because executable code is located in the text section of an object file). Additionally, the capitalization of the symbol type ...
