Semantic Error In Coding
Such things as incorrect variable types or sizes, nonexistent variables, subscripts out of range, and the like, are semantic errors. 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. The syntax of the source code may be valid, but the algorithm being employed is not. The code is correct and bug-free and does exactly what you've intended. useful reference

A compiler typically has a lexical analyzer (tokenizer) and a parser as distinct components; both of them deal with syntax. –Keith Thompson Feb 12 '14 at 19:34 add a comment| protected It also is a one-look ahead parser, meaning that at the most it is never looking more than one symbol ahead of the current context.

sentence is syntactically and semantically correct, but its meaning may not be what was intended. (English) ‘Flying planes can be dangerous’ can have two meanings i.e. 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. They are not really independent universal concepts, but a related pair of words that, when you are in a particular context, indicate opposite directions. https://wci.llnl.gov/codes/basis/manual/node53.html But in computer science, semantics is a meaning of a language, not a particular program. –SK-logic Oct 12 '11 at 14:15 add a comment| up vote -3 down vote Very short
