Passing reference in c? <p>I was just wondering if someone could answer this review question I have for an upcoming exam. Unfortunately I do not have an answer key to double check and I wanted to be sure my answer was correct. Here is the question:</p> <p>Which of the following correctly passes the reference to the variable <code>int max</code> to the function <code>f</code>?</p> <pre><code>a) f(max); b) f(*max); c) f(&amp;max); d) f(ref_max); e) None of the above </code></pre> <p>My best guess would be c. Unless I'm completely wrong, I'm sure a, d, e are not right and it's not asking me to dereference anything like choice b. I'm sorry if I broke any posting rules with this website and I know its probably an easy question for most of you.</p>
