  3. Pretty-printing - Wikipedia

    en.wikipedia.org/wiki/Prettyprint

    HTML source code, pretty-printed to better show the hierarchical relationships of its elements (called tags) Pretty-printing in markup language instances is most typically associated with indentation of tags and string content to visually determine hierarchy and nesting. Although the syntactical structures of tag-based languages do not ...

  4. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.

  5. "Hello, World!" program - Wikipedia

    en.wikipedia.org/wiki/"Hello,_World!"_program

    For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...

It is also possible to customize their display on the monitor. The most common non-printable characters in word processors are pilcrow, space, non-breaking space, tab character etc. [1] [2]

    But unreachable code may also be part of a complex library, module or routine where it is useful to others or under conditions which are not met in a particular scenario. An example of such a conditionally unreachable code may be the implementation of a general string formatting function in a compiler's runtime library, which contains complex ...

  8. Talk:"Hello, World!" program/Archive 1 - Wikipedia

    en.wikipedia.org/wiki/Talk:"Hello,_world...

    The article is about a program, not an application. Showing window with a string and an OK button is meaningless and not representative of most hello world programs, which would have a command-line interface. Lastly, I object to the claim that a code example is gobbledegook in this context.

  9. Callback (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Callback_(computer...

    The following REBOL/Red code demonstrates callback use. As alert requires a string, form produces a string from the result of calculate; The get-word! values (i.e., :calc-product and :calc-sum) trigger the interpreter to return the code of the function rather than evaluate with the function. The datatype! references in a block!
