this is a question in the past exam: Roughly, how many standard header files are defined by the C11 standard: A. 10 B. 30 C. 100 D. 300 was this information accessible on the lecture slides? and if so will these types of questions come out in the midsem? just wondering since it doesn't really assess anything more just like a general knowledge question.

All of the questions in this sample test have been taken from past tests. It's not a question to be answered with just general knowledge - ask a random student on campus, and they'll have a 1:4 chance of getting it right. It's a question to be answered through your experience gained in the unit. What is *your* answer to the question, and how did you reach that value?

in light of adding clarity to the question, would it be fair to deduct that The C11 standard defines 29 standard header files, covering essential functionalities required for C implementations, as explicitly listed in the ISO/IEC 9899:2011 specification, so thefore it would be b?

ANONYMOUS wrote: B) is certainly the correct answer. Yes, it's undoubtably defined in the (huge) standards document, but there is no requirement to read it to answer the question. We've highlighted that C is quite a small language by contemporary standards (compare it to either Python and Java, and the number of their standard modules or packages). In lectures, labs, and workshops we've used (about) 8 standard header files. The document https://en.kompf.de/cplus/cliblist.html linked from our "Information Resources" page, lists the contents of at least 15 header files (it's describing an older version of C, but standards never result in language/library features shrinking). When this question was asked on a past mid-semester test, the great majority of students answered it correctly.
