It is one of the hardest concepts to learn, especially http://stackoverflow.com/questions/846103/runtime-vs-compile-time for people without much background in programming languages. To approach this problem, I find it helpful to ask What invariants does the program satisfy? What can go wrong in this phase? If the phase succeeds, what are the postconditions (what do we know)? What are the inputs and outputs, if any? Compile time The program need not satisfy any invariants. In fact, it needn't be a well-formed program at all. You could feed this HTML to the compiler and watch it barf... What can go wrong at compile time: Syntax errors Typechecking errors (Rarely) compiler crashes If the compiler succeeds, what do we know? The program was well formed---a meaningful program in whatever language. It's possible to start running the program. (The program might fail immediately, but at least we can try.) What are the inputs and outputs? Input was the program being compiled, plus any header files, interfaces, libraries, or other voodoo that it needed to import in order to get compiled. Output is hopefully assembly code or relocatable object code or even an executable program. Or if something goes wrong, output is a bunch of error messages. Run time We know nothing about the program's invariants---they are whatever the programmer put in. Run-time invariants are rarely enforced by the compiler alone; it needs help from the
is the difference between an error and a fatal error?UpdateCancelAnswer Wiki5 Answers David Brower, writing C since 1980, on and off UNIX since 1983.Written 56w agoTypically a plain error is recoverable in https://www.quora.com/What-is-the-difference-between-an-error-and-a-fatal-error some way that lets the program continue, and a fatal error is one from which the programmer sees no escape, or insanity to continue. "I can't be bothered to handle this"For example, failure https://scn.sap.com/thread/776359 to allocate memory is often handled as a fatal error. In principle, it could cause some activity that would reclaim memory by flushing caches or something like that. But often that masks the syntax error real problem, that the machine is out of memory, and normal operation is going to keep running into it. (Or there's a memory leak)There's a good argument that fatal errors are a good thing for ultimate reliability, because it forces them out in a highly visible way right at the time of error, rather than letting badness propagate. This makes it easier to debug and informs the difference between syntax programmer that the judgement that it was too hard to handle was a mistake, and it darned well better get handled.

James H. Kelly, I've been coding since I was in second grade.Written 56w agoA fatal error is one that kills your program (app / server / site / whatever it is). It renders it unusable, either by crashing or by putting it in some state whereby it can't do it's usable work.A "non-fatal" error is one where something messes up, but the program can continue to do what it's supposed to do (serve other users not requesting the thing that called the error, for example).654 Views · View Upvotes · Answer requested by 1 person Andrew Daviel, occasional coder in PerlWritten 58w agoIn c

Uwe Schieferstein Mar 11, 2008 7:02 AM (in response to abaper learner) Currently Being Moderated HelloA program with a syntax error cannot be executed.The program with a runtime error can be executed but dumps under certain conditions.Example: You have a division statement in your program. If for some reason the denominator becomes zero then you will get a runtime error (something like DIVISION_BY_ZERO).Syntax errors are static error that can be detected by the compiler.Runtime errors are dynamic error that cannot be detected by the compiler.Regards Uwe Alert Moderator Like (0) Re: what is the difference between syntax error runtime error?
