April Learn how and when to remove this template message In CPS, each procedure takes an extra argument representing what should be done with the result the function is calculating.

This, along with a restrictive style prohibiting a variety of constructs usually available, is used to expose the semantics of programs, making them easier to analyze. The key to CPS is to remember that a every function takes an extra argument, its continuation, and b every argument in a function call must be either a variable or a lambda expression not a more complex expression.

This has the effect of turning expressions "inside-out" because the innermost parts of the expression must be evaluated first, so CPS explicates the order of evaluation as well as the control flow. Some examples of code in direct style and the corresponding CPS appear below.

These examples are written in the Scheme programming language ; by convention the continuation function is represented as a parameter named "k": There is some variety between compilers in the way primitive functions are provided in CPS. The translations shown above show that CPS is a global transformation.

Any function calling a CPS-ed function must either provide a new continuation or pass its own; any calls from a CPS-ed function to a non-CPS function will use implicit continuations. Thus, to ensure the total absence of a function stack, the entire program must be in CPS.

CPS in Haskell [ edit ] In this section we will write a function that calculates hypotenuse using Pythagorean theorem. Traditional pyth function looks like this: Function will get another argument of function type and its return type depends on that function: And so on until we reach the result of our calculations.

Factorial - Rosetta Code

To get the result of this function we can pass id function as a final argument which returns the value that was passed to it unchanged: This module provides Cont type, which implements Monad and some other useful functions.

The following snippet shows pyth' function using Cont type: This function has the only argument of a function type; that function argument accepts the function too, which discards all computations going after its call.

For example let's break the execution of pyth function if at least one of its arguments is negative returning zero: Callback computer programming Programming with continuations can also be useful when a caller does not want to wait until the callee completes.

For example, in user-interface UI programming, a routine can set up dialog box fields and pass these, along with a continuation function, to the UI framework. This call returns right away, allowing the application code to continue while the user interacts with the dialog box.Topical Software¶.

This page indexes add-on software and other resources relevant to SciPy, categorized by scientific discipline or computational topic. Write a function to return the factorial of a number. Solutions can be iterative or recursive. Following examples display other ways to calculate the factorial function: Recursive program Factorial2;.

In Lisp, the output of every function is the "last line executed in the function". Unless you use some syntax manipulation like "return" or "return-from", which is not the Lisp-way.

The (format t "your string") will always return 'NIL as its output. C Program to Find Factorial of a Number Using Recursion.

Example to find factorial of a non-negative integer (entered by the user) using recursion. 5 is passed to the multiplyNumbers() function from the same function (recursive call).

In each recursive call, the value of argument n is decreased by 1. When the value of n is less than 1.
