Semantic Errors In Language
In the "x" assignament, "-" means the "substraction" operation, In the "y" assignament, "-" means the "negative sign" operation. There is no way for the compiler to detect them. I don't think so.) It's rare that the compiler can tell what you want, as opposed to what you asked for, with any accuracy. Or: mylist = mylist.sort() (did you really want mylist to be set to None?

The syntax is flawless, but it has no meaning. Semantic Error Definition A graph of abstract resources as syntax encodes a conceptual model as semantic. Semantics is what those tokens mean (usually, what a particular arrangement of tokens means). http://stackoverflow.com/questions/7849684/what-is-semantic-errors-in-c-language-give-some-examples Most of the compilers are unable to catch semantic errors though Java does catch some of such errors like type conversion.

I wondered the same, was too lazy to search the internet for this, and obviously never asked. –KK. You can see a semantic error when the syntax of your code is correct but the code usage isn't correct. calculating the wrong result because the code says add 1 instead of add 2). Semantic Errors In Speech Syntax errors occur during the parsing of input code, and are caused by grammatically incorrect statements.
A compiler will check your syntax for you (compile-time errors), and derive the semantics from the language rules (mapping the syntax to machine instructions say), but won't find all the semantic How is being able to break into any Linux machine through grub2 secure? word order.

post a question about a particular issue, but don't ask for blanket definitions for numerous topics –KevinDTimm Oct 21 '11 at 12:59 1 Yeah... Developers care about design because a good design is about reducing complexity by abstracting complex behaviors and interactions, and different kinds of problems lend themselves to different semantics. Not the answer you're looking for? Semantics are supplied by the developer, and are only meaningful to him. –kylben Oct 12 '11 at 13:31 3 @kylben, I am not contradicting myself, because I never said that
Syntatically valid structure does not imply it to be semantically valid. Applying scoping incorrectly: Any variable you declare inside a method has the same scope -- visibility to other parts of the application, in other words -- as the method. Syntax defines how these are expressed in characters. I've just "mv"ed a 49GB directory to a bad file path, is it possible to restore the original state of the files?
