  2. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    A function call using named parameters differs from a regular function call in that the arguments are passed by associating each one with a parameter name, instead of providing an ordered list of arguments. For example, consider this Java or C# method call that doesn't use named parameters:

  3. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    A recursive function named foo, which is passed a single parameter, x, and if the parameter is 0 will call a different function named bar and otherwise will call baz, passing x, and also call itself recursively, passing x-1 as the parameter, could be implemented like this in Python:

  4. Evaluation strategy - Wikipedia

    en.wikipedia.org/wiki/Evaluation_strategy

    In a programming language, an evaluation strategy is a set of rules for evaluating expressions. [1] The term is often used to refer to the more specific notion of a parameter-passing strategy [2] that defines the kind of value that is passed to the function for each parameter (the binding strategy) [3] and whether to evaluate the parameters of a function call, and if so in what order (the ...

  5. Apply - Wikipedia

    en.wikipedia.org/wiki/Apply

    There are other common notational differences as well; for example Apply is often called Eval, [6] even though in computer science, these are not the same thing, with eval distinguished from Apply, as being the evaluation of the quoted string form of a function with its arguments, rather than the application of a function to some arguments.

  6. Function (computer programming) - Wikipedia

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

    Assign an identifier, name, to a function; Define formal parameters with a name and data type for each; Assign a data type to the return value, if any; Specify a return value in the function body; Call a function; Provide actual parameters that correspond to a called function's formal parameters; Return control to the caller at the point of call

  7. Parameter (computer programming) - Wikipedia

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

    Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely, a parameter is a type, and an argument is an instance.

  8. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    The call to d->f1() passes a B1 pointer as a parameter. The call to d->f2() passes a B2 pointer as a parameter. This second call requires a fixup to produce the correct pointer. The location of B2::f2 is not in the virtual method table for D. By comparison, a call to d->fnonvirtual() is much simpler: (*

  9. Tail call - Wikipedia

    en.wikipedia.org/wiki/Tail_call

    However, for language implementations which store function arguments and local variables on a call stack (which is the default implementation for many languages, at least on systems with a hardware stack, such as the x86), implementing generalized tail-call optimization (including mutual tail recursion) presents an issue: if the size of the ...
