FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A program may be syntactically correct and no warning reported but still give a wrong answer, is a program that contain a bug. A bug is either a programming error (i.e. + instead of-) or a logical error where you cannot perform an operation sequence in a logical manner.

Detailed explanation-2: -Syntax errors are mistakes in the source code, such as spelling and punctuation errors, incorrect labels, and so on, which cause an error message to be generated by the compiler. These appear in a separate error window, with the error type and line number indicated so that it can be corrected in the edit window.

Detailed explanation-3: -You’d have thought the argument was settled ages ago when everyone agreed that In 1947, the Harvard Faculty at the Computation Laboratory traced an error in the Mark II computer to a moth trapped in a relay, thereby coining the term ‘bug’. This bug was carefully removed and taped to the logbook which still exists.
