  2. Parameter (computer programming) - Wikipedia

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

    More precisely, one may distinguish three types of parameters or parameter modes: input parameter s, output parameters, and input/output parameter s; these are often denoted in, out, and in out or inout. An input argument (the argument to an input parameter) must be a value, such as an initialized variable or literal, and must not be redefined ...

  3. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    Without named parameters, optional parameters can only appear at the end of the parameter list, since there is no other way to determine which values have been omitted. In languages that support named optional parameters, however, programs may supply any subset of the available parameters, and the names are used to determine which values have ...

    Unboxing is the operation of converting a value of a reference type (previously boxed) into a value of a value type. [15] Unboxing in C# requires an explicit type cast. Example:

  9. Generator (computer programming) - Wikipedia

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

    In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop.All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.
