In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
Primitive recursive function. In computability theory, a primitive recursive function is, roughly speaking, a function that can be computed by a computer program whose loops are all "for" loops (that is, an upper bound of the number of iterations of every loop is fixed before entering the loop). Primitive recursive functions form a strict ...
Returns 1 if number is positive, 0 if it is 0, and −1 if it is negative [16] SIN: number: EXTENDED MODE then Q: Function Returns the sine of number [34] STEP: number: SYMBOL SHIFT+D: Other Indicates the interval used by a FOR statement, [44] for example FOR n = 2 TO 6 STEP 2 will skip n=3 and n=5 in the loop STOP: SYMBOL SHIFT+A: Command
v. t. e. Mac OS X 10.0 (code named Cheetah) is the first major release of macOS, Apple's desktop and server operating system. It was released on March 24, 2001, for a price of $129 after a public beta. Mac OS X was Apple's successor to the classic Mac OS. It was derived from NeXTSTEP and FreeBSD, and featured a new user interface called Aqua ...
Control flow. v. t. e. In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
Iterator. In computer programming, an iterator is an object that progressively provides access to each item of a collection, in order. [1][2][3] A collection may provide multiple iterators via its interface that provide items in different orders, such as forwards and backwards. An iterator is often implemented in terms of the structure ...
macOS. macOS Catalina (version 10.15) is the sixteenth major release of macOS, Apple Inc. 's desktop operating system for Macintosh computers. It is the successor to macOS Mojave and was announced at WWDC 2019 on June 3, 2019 and released to the public on October 7, 2019.
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [73] and metaobjects). [74] Many other paradigms are supported via extensions, including design by ...
