- What is the difference between syntax and semantics in programming . . .
3 HIGH LEVEL SEMANTICS Finally, at a higher level, semantics is concerned with what the code is intended to achieve - the reason that the program is being written This can be expressed as pseudo-code which could be implemented in any complete language For example:
- In terms of programming, what do semantics mean?
Static semantics tells you which programs that are grammatical are also well formed Many languages either have no static semantics (Scheme, Ruby, Python, Icon, Lua, Perl) or have a static semantics that is primarily about implementing a type system (Java, C, C#, Haskell) "Declaration required before use" is another possible static semantics
- What does You are playing with semantics mean? - Answers
Semantics and pragmatics both study the meaning of language Semantics focuses on literal meaning, while pragmatics examines how meaning is influenced by context, intention, and speaker beliefs
- c++ - What is move semantics? - Stack Overflow
Intermediate C++ programmers are probably at least somewhat familiar with std::auto_ptr, and because of the "move semantics" it displays, it seems like a good starting point for discussing move semantics in C++11 YMMV What is a move? The C++98 standard library offers a smart pointer with unique ownership semantics called std::auto_ptr<T>
- c++ - Move semantics - what its all about? - Stack Overflow
Move semantics define the behaviour of certain operations Most of the time they are contrasted with copy semantics, so it would be useful to define them first Assignment with copy semantics has the following behaviour: Copy semantics assert(b == c); a = b; assert(a == b b == c); i e a ends up equal to b, and we leave b unchanged
- Are semantics and syntax the same? - Stack Overflow
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, comprehended by his public, general convention by his public and digestible to the machine-computer Semantics should be agreed upon, are conceptual, must be implementable to both
- Simple definition of semantics as it is commonly used in relation to . . .
Operational Semantics is probably closest to the way most people informally model the semantics, having each fragment of code run through an interpreter and changing the state of an abstract routine This approach breaks down in many models where concurrency or nondeterminism, etc , so there are other sematics better suited to these situations
- c++ - What is semantics? - Stack Overflow
The word semantics is used to describe an underlying meaning of something You can say that an operation has the move semantics when it transfers an object state from one object to another In reality of course what happens is some pointers are probably copied over and that's it, but semantically your object has been moved
