These may be using the wrong variable, the wrong operation, or operations in the wrong order. share|improve this answer answered Dec 13 '12 at 19:15 Jakob 42427 add a comment| up vote 3 down vote If it can be described in BNF (Backus-Naur Form) or something similar, Compile Errors Compile errors are those errors that occur at the time of compilation of the program. People usually stop at some level and take it as semantic, but in the end there is no final semantic unless some human being interprets the data in his mind. have a peek here

It doesn't interpret semantics, it interprets syntax. Seasonal Challenge (Contributions from TeXing Dead Welcome) Why can't the second fundamental theorem of calculus be proved in just two lines? Semantics is the meaning associated with syntactically correct string of symbols with no static semantic error i.e. Or, perhaps "it's just semantics!"

Adding 1 rather than 2 is what I'd call a logical error. –Keith Thompson Oct 13 '11 at 0:37 3 @Keith - but logic (as in "logical error") is semantics. calculating the wrong result because the code says add 1 instead of add 2). true_value : false_value VB.NET: If(condition, true_value, false_value) -- Different syntax, same semantics. If one goes beyond the realm of data, this nesting can be virtually infinite, as described by Umberto Eco as "unlimited semiosis".

There is a third class, which can be the most expensive: 3) Design errors. And sometimes the line between the two can be blurry. These are invalid code the compiler doesn't understand, e.g.

It's like a "Captain Kirk" v.s. "Dr Spock" question.

Runtime Errors The following are three Java examples for showing what are syntax error, semantic error, and runtime error. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. share|improve this answer edited Mar 15 '13 at 8:29 Kilian Foth 66.4k21180213 answered Mar 15 '13 at 7:26 IcyFlame 25325 3 Down voter: explain why you have down voted. –IcyFlame But semantically it is wrong, because this statement has no conceivable or correct meaning.

Syntactic Error If a program contains syntax error, it will not pass compilation. As soon as one tries to express semantic in form of data, it becomes syntax. An RDF graph (the stuff with URI References) as syntax encodes a graph of abstract resources as semantic. 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

Therefore a sentence that seemingly makes no syntactic sense, can have meaning when using semantic cues. There is a third class, which can be the most expensive: 3) Design errors. The sentence "Baby milk drinks" does not have a syntactic meaning, but through semantics most people would interpret it as meaning " Baby drinks milk " as our prior knowledge tells See, for example, GLR-based C++ parsers. –SK-logic Oct 12 '11 at 11:48 2 @EvanPlaice, what are you talking about?

(Programming) ‘the computer will not generate any error messages, but it will not do what you A semantic error is also called a "logic error;" however, some programmers believe a logic error produces erroneous data, whereas a semantic error yields nothing meaningful at all. A compiler/interpreter doesn't care a whit about your design, and in any code compiled down to machine level you'd have a hard time deducing the design.
