If a program does not compile, should it get a mark of zero?
This answer assumes that the course's goal is to teach programming (as opposed to teaching advanced algorithms or numerics etc. to which the programming would only be an end). In that case I'd hold: ...

What's the benefit of prohibiting the use of techniques/language constructs that have not been taught?
Rules like this are generally instituted because the teacher is attempting to teach a concept made moot by one of these constructs. For example, as a teacher, if you're teaching bitwise operators and ...

Why teach C using scanf without talking about command line arguments?
I think that the rationale is so you don't have to introduce arrays and array notation on day 1. Typically, arrays enter into the picture at roughly the same time as loops, which would take place a ...
