  2. Stack (abstract data type) - Wikipedia

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

    For example, if n = 3, items 1, 2, and 3 on the stack are moved to positions 2, 3, and 1 on the stack, respectively. Many variants of this operation are possible, with the most common being called left rotate and right rotate. Stacks are often visualized growing from the bottom up (like real-world stacks).

    en.wikipedia.org/wiki/Whitespace_(programming...

    A numeric value is represented as a sequence of space and tab characters that represent 0 and 1 respectively and terminated by a linefeed. The first character represents the sign of the value – space for positive and tab for negative. Subsequent characters before the terminator represent the binary digits of a value. For example:

  4. Call stack - Wikipedia

    en.wikipedia.org/wiki/Call_stack

    The stack of such operands, rather like that in an RPN calculator, is called an evaluation stack, and may occupy space in the call stack. Enclosing subroutine context Some programming languages (e.g., Pascal and Ada ) support declaration of nested subroutines , which are allowed to access the context of their enclosing routines, i.e., the ...

  5. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    Many of the operators containing multi-character sequences are given "names" built from the operator name of each character. For example, += and -= are often called plus equal(s) and minus equal(s), instead of the more verbose "assignment by addition" and "assignment by subtraction". The binding of operators in C and C++ is specified (in the ...

  6. Stack-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Stack-oriented_programming

    PostScript is an example of a postfix stack-based language. An expression example in this language is 2 3 mul ('mul' being the command for the multiplication operation). Calculating the expression involves understanding how stack orientation works. Stack orientation can be presented as the following conveyor belt analogy.

    Record (also called a structure or struct), a collection of fields Product type (also called a tuple), a record in which the fields are not named; String, a sequence of characters representing text; Union, a datum which may be one of a set of types

  8. List of Unicode characters - Wikipedia

    en.wikipedia.org/wiki/List_of_Unicode_characters

    95 characters; the 52 alphabet characters belong to the Latin script. The remaining 43 belong to the common script. The 33 characters classified as ASCII Punctuation & Symbols are also sometimes referred to as ASCII special characters. Often only these characters (and not other Unicode punctuation) are what is meant when an organization says a ...

  9. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    A character in single quotes (example: 'R'), called a "character constant," represents the value of that character in the execution character set, with type int. Except for character constants, the type of an integer constant is determined by the width required to represent the specified value, but is always at least as wide as int.
