  2. Comparison of programming languages (associative array)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In Lua, "table" is a fundamental type that can be used either as an array (numerical index, fast) or as an associative array. The keys and values can be of any type, except nil. The following focuses on non-numerical indexes. A table literal is written as { value, key = value, [index] = value, ["non id string"] = value }. For example:

    Fortran 77: A non-comment line is a continuation of the prior non-comment line if any non-space character appears in column 6. Comment lines cannot be continued. Comment lines cannot be continued. COBOL : String constants may be continued by not ending the original string in a PICTURE clause with ' , then inserting a - in column 7 (same ...

  4. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...

  5. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

  6. Comment (computer programming) - Wikipedia

    [5] [6] [7] A line comment ends at the end of the text line. In modern languages, a line comment starts with a delimiter but some older languages designate a column at which subsequent text is considered comment. [7] Many languages support both block and line comments – using different delimiters for each.

    # In the following example, the value for "evenKey" is "This is on one line\". evenKey = This is on one line \\ # This line is a normal comment and is not included in the value for "evenKey". # If the number of backslash ('\') is odd, then the next line is included in the value.

  8. Property list - Wikipedia

    en.wikipedia.org/wiki/Property_list

    Comments are allowed as: /* This is a comment */ and // This is a line comment. As in C, whitespace are generally insignificant to syntax. Value statements terminate by a semicolon. One limitation of the original NeXT property list format is that it could not represent an NSValue (number, Boolean, etc.) object.

  9. Array (data type) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_type)

    An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...
