Bitwise copy semantics c

Bitwise copy semantics c

Does copy elision and RVO would still work for classes without move constructors? Yes, RVO still kicks in. Actually, the compiler is expected to pick: RVO (if possible) Move construction (if possible) Copy construction (last resort) Why can t STL internally leverage move semantics to improve such operations internally using operations like copy elision or RVO which doesn t…

Semantics and syntax relationship

Semantics and syntax relationship

It is not easy to describe the relation between syntax and semantics, but it is probably easy to say why that is not easy: there are different perspectives about syntax and semantics, so the relation depends on what you understand by form and meaning, structure and content. If you look at the history of Chomskyan linguistics, you will find the chapter in which a group of people…

Semantics VS syntax examples

Semantics VS syntax examples

Explanations above are vague on the semantics side, semantics could mean the different elements at disposition to build arguments of value(these being comprehensible, to end-user man and digestible to the machine). Of course this puts semantics and the programmer-editor-writer-communicator in the middle: he decides on the semantics that should be ideally defined to his public…

Semantics and Grammar

Semantics and Grammar

Author(s): Karen Sp\ arck Jones Semantic grammar is contrasted with conventional grammars as it relies predominantly on semantic rather than syntactic categories, e.g., MESSAGE, PATIENT-TYPE, HAVE, DISEASE-TYPE. In some cases the semantic categories and structures are merely cosmetic re-labellings of conventional syntactic categories and structures, but more thorough semantic…

Definition semantics

An extension of the current Web that provides an easier way to find, share, reuse and combine information. It is based on machine-readable information and builds on XML technology s capability to define customized tagging schemes and RDF s ( esource escription ramework ) flexible approach to representing data. The Semantic Web provides common formats for the interchange of…

Semantics error in c

Semantics error in c

I think it has something to do with the workspace/.metadata. I had the problem of semantic errors reported but Hello World compiles and runs. I deleted the project, created another one, same error reporting. Reinstalled CDT, same thing. Deleted the workspace, shut down Eclipse, restarted, created new hello world, same thing. Deleted the workspace again, shut down Eclipse again…

Example of semantics in Linguistics

Semantics focuses on the relationships between words and phrases, as well as the rules for combining words in order to create phrases and sentences. There s a seemingly endless list of terms for various relationships between words, so we ll just list some of the most important and interesting ones below. homonyms - These are words pronounced (and sometimes also spelled) the…

Nonsemantic

Nonsemantic

At least a few of the 120 analogies (questions) on your MAT will involve non-semantic word relationships. What this means is that the connection between the words has nothing to do with their meaning. (The adjective semantic means of or relating to the meanings of words and phrases. This type of MAT question typically focuses either on letter patterns or on phonetics (how…

C using move semantics

C using move semantics

In which I briefly mention what pure functional programming is, explain why this can be slow in C++, and use move semantics to solve that problem. Be warned that this post is a bit longer than usual for this blog, and that it assumes more knowledge of C++11 than my posts usually do. Pure functional programming is programming without state. In short, functions should not modify…

STL value semantics

STL value semantics

Most container types want to abstract the particular storage strategy, be it linked list, vector, tree-based or what have you. For this reason, you re going to have trouble with both possessing and consuming the aforementioned cake (i.e., the cake is lie (NB: someone had to make this joke)). So what to do? Well there are a few cute options, but most will reduce to variants…

How speaker intention and hearer interpretation affect meaning OR the study of utterance meaning OR how the meanings of the things we say are shaped by context. 1. Interrogatives (questions) 2. Imperatives (commands) 3. Declaratives (statements) Utterance intended to convey communicative force. Utterance whose meaning is the sum of its parts, the literal meaning. Eg: Has it…
