title: Are the "C mock tests" at tutorialspoint correct?
body: <p>Since I've been coding C for well over 20 years, I think it was high time for me to take a test! To see if I've learnt anything at all, or if I'm just some fraud posting free but incorrect advice to beginners on the Internet.</p>
  <p>This site (I'm not affiliated) offers free C tests. <a href="https://www.tutorialspoint.com/cprogramming/cprogramming_mock_test.htm" rel="nofollow noreferrer">https://www.tutorialspoint.com/cprogramming/cprogramming_mock_test.htm</a>.</p>
  <p>I took test 1 and failed spectacularly with only 34 out of 50! Is this it? Do I have to give up my C programmer career? How good is this Tutorialspoint site and its tests?</p>
  <p>Specifically, I failed to answer Q7, Q9, Q10, Q14, Q16, Q17, Q19, Q21, Q27, Q28, Q31, Q32, Q33, Q35, Q38, Q46 with the answer expected by the test. What are the correct answers to those questions?</p>
  <p>Also, when I compile the questions on my conforming implementation C compiler (<code>gcc -std=c11 -pedantic-errors</code>) none of them will even pass compilation. Why is that? Am I and/or my compiler broken? Or is this site not very good at all?</p>
