A script that lets the sprite say Hello, World! then stops the script in Scratch 2.0. In Scratch 2.0, the stage area is on the left side, with the programming blocks palette in the middle, and the coding area on the right. Extensions are in the "More Blocks" section of the palette. [22] The web version of Scratch 2.0 introduced project autosaving.
In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
CEL is an open source LISP-based reasoner (Apache 2.0 License). Cerebra Engine was a commercial C++-based reasoner, acquired in 2006 by webMethods. FaCT++ is a free open-source C++-based reasoner. KAON2 is a free (for non-commercial use) Java-based reasoner, offering fast reasoning support for OWL ontologies.
Microsoft's simplified variant of BASIC, it is designed to help students who have learnt visual programming languages such as Scratch learn text-based programming. [8] The associated IDE provides a simplified programming environment with functionality such as syntax highlighting, intelligent code completion, and in-editor documentation access. [9]
Scratch (programming language), an educational programming language developed by the MIT Media Lab; Scratch space, space on the hard disk drive that is dedicated for only temporary storage; Scratching, a technique used in recrystallization; Scratch reflex, a response to activation of sensory neurons
ScratchJr is a derivative of the Scratch language, which has been used by over 10 million people worldwide. Programming in Scratch requires basic reading skills, however, so the creators saw a need for another language which would provide a simplified way to learn programming at a younger age and without any reading or mathematics required.
In Boolean logic, logical NOR, [1] non-disjunction, or joint denial [1] is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both p and q are false.
In computer programming, an operator is a programming language construct that provides functionality that may not be possible to define as a user-defined function (i.e. sizeof in C) or has syntax different than a function (i.e. infix addition as in a+b). Some languages allow a language-defined operator to be overridden with user-defined ...
