[Year 12 SofDev] compiler question

[David Dawson]

Well, I am very sorry to disagree with you Mark – it is a rare event - but poorly validated input is not a result of a syntax error – but it does create a runtime error.
Since the program has compiled there is no syntax error in the actual code.

But the trigger of the crash was incorrect syntax of the input into the program (which is acting as a compiler/interpreter)...

Hi Andrew,

I'm with you. The program runs, so no syntax error. The program crashes when given an incorrect input, that's a run time error for me.

Hi all,
I have purchased the IARTV trial exams and am wondering about one of their multi-choice answers.Your help is, as always, appreciated.

The question asks about a function written which is called “POP”, but “when testing his stack Alan accidentally types in PIP and the program crashes”.
The multi-choice answers has us choose from runtime error or syntax error.

They suggest the answer is syntax error (and explain that a name, expression etc…that the compiler cannot understand causes a syntax error)

Now, if the program IS RUNNING and THEN crashes, does that not imply that it compiled? Therefore, it is a runtime error (where validation of input was not handled) or am I thinking too language specifically?

Thanks
