  3. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    This means a string cannot contain the zero code unit, as the first one seen marks the end of the string. The length of a string is the number of code units before the zero code unit. [1] The memory occupied by a string is always one more code unit than the length, as space is needed to store the zero terminator.

  4. Rope (data structure) - Wikipedia

    en.wikipedia.org/wiki/Rope_(data_structure)

    The split point is at the end of a string (i.e. after the last character of a leaf node) The split point is in the middle of a string. The second case reduces to the first by splitting the string at the split point to create two new leaf nodes, then creating a new node that is the parent of the two component strings.

  5. Escape sequences in C - Wikipedia

    en.wikipedia.org/wiki/Escape_sequences_in_C

    To demonstrate the value of the escape sequence feature, to output the text Foo on one line and Bar on the next line, the code must output a newline between the two words. The following code achieves the goal via text formatting and a hard-coded ASCII character value for newline (0x0A). This behaves as desired with the words on sequential lines ...

  6. Box-drawing characters - Wikipedia

    en.wikipedia.org/wiki/Box-drawing_characters

    Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment.

  7. GW-BASIC - Wikipedia

    en.wikipedia.org/wiki/GW-BASIC

    The data type of variables can be specified with a character at the end of the variable name: A$ is a string of characters, A% is an integer, etc. Groups of variables can also be set to default types based on the initial letter of their name by use of the DEFINT, DEFSTR, etc., statements.

  8. Stack (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Stack_(abstract_data_type)

    Initially the size of the stack is zero. A stack pointer (usually in the form of a processor register) points to the most recently referenced location on the stack; when the stack has a size of zero, the stack pointer points to the origin of the stack. The two operations applicable to all stacks are:

  9. Template:Graph:Lines - Wikipedia

    This graph draws one or more independent numeric data series as lines. The data must be stored on Commons' Data namespace or come from Wikidata Query Service. Template parameters Parameter Description Type Status Table type tabletype Specifies the type of the table data. "tab" (default) uses data namespace on commons, without the data: prefix. "query" sends request to wikidata query service ...
