  2. 3 ft 6 in gauge railways - Wikipedia

    en.wikipedia.org/wiki/3_ft_6_in_gauge_railways

    In Australia, this gauge is typically referred to as narrow gauge in comparison to 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge or 5 ft 3 in (1,600 mm) broad gauge. In some instances, simply 3 foot 6 inch — or in rarer cases medium gauge — is used to distinguish it from other narrow gauges.

    en.wikipedia.org/wiki/Variable-length_array

    In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C , the VLA is said to have a variably modified data type that depends on a value (see Dependent type ).

    San Diego Electric Railway (converted to standard gauge) (defunct) San Francisco cable car system (U.S. National Historic Landmark status) (operating) Southern California Railway Museum (standard gauge lines, 3 ft (914 mm) gauge lines, and dual gauge lines with standard gauge track and 3 ft 6 in (1,067 mm) gauge track also present) (operating ...

  5. List of 2 ft 3 in gauge railways - Wikipedia

    en.wikipedia.org/wiki/List_of_2_ft_3_in_gauge...

    Standard gauge is defined as 1,435 mm (4 ft 8 + 1 ⁄ 2 in), and narrow gauge as any gauge less than that distance. In Britain, standard gauge is used for all main line routes and the majority of urban light rail.

  6. NumPy - Wikipedia

    en.wikipedia.org/wiki/NumPy

    NumPy (pronounced / ˈ n ʌ m p aɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3]

  7. Constructor (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Constructor_(object...

    The initializer list is required if you have const or reference type data members, or members that do not have parameterless constructor logic. Assignments occur according to the order in which data members are declared (even if the order in the initializer list is different). [3]

  8. Lazy initialization - Wikipedia

    en.wikipedia.org/wiki/Lazy_initialization

    height ^ height ifNil: [height:= 2.0]. The 'non-lazy' alternative is to use an initialization method that is run when the object is created and then use a simpler accessor method to fetch the value. initialize height := 2.0 height ^ height
