Typical errors might be an illegal character in the input, a missing operator, two operators in a row, two statements on the same line with no intervening semicolon, unbalanced parentheses, a Syntax is defined by the language grammar, and the two operators are specified in different sections of the grammar. If one goes beyond the realm of data, this nesting can be virtually infinite, as described by Umberto Eco as "unlimited semiosis". syntax semantics share|improve this question asked Oct 12 '11 at 5:28 gsingh2011 69211016 7 A bit of mandatory reading: en.wikipedia.org/wiki/Denotational_semantics en.wikipedia.org/wiki/Operational_semantics en.wikipedia.org/wiki/Abstract_syntax –SK-logic Oct 12 '11 at 9:03 6 More about the author

Syntax defines how these are expressed in characters. Semantic Error Definition Tell a friend about us, add a link to this page, or visit the webmaster's page for free fun content. For example, the concept of pointer arithmetic is part of C's semantics; the way the + and - operators can be used to express pointer operations are part of its syntax. this content 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.

These are valid code the compiler understands, but they do not what you, the programmer, intended. Some semantic checks can be done by the compiler - particularly type checking - so I agree that compilers don't only find syntax errors, but Chris only said "won't find all
Semantic errors occur during the execution of the code, after it has been parsed as grammatically correct. 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. calculating the wrong result because the code says add 1 instead of add 2). This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.
