Error Diagnostics Definition/Meaning:
Information that is presented following the detection of some
error condition and is mainly intended to assist in identifying the cause of the
error. As an example, consider the compilation and subsequent execution of some
program. Syntactic errors in the program, i.e. failure of the program to conform
to the defined syntax of the programming language, would normally be detected
at compilation time, and the compiler would then generally produce error
diagnostics to indicate both the location and the kind of error (unrecognized
statement, undeclared identifier, etc.).
At execution time certain kinds of
semantic errors may be detected, i.e. improper behavior of a program that
conforms to the defined syntax of the language. In this case the error
diagnostics may be produced by some run-time system.
