Comments in C are enclosed by slash/star pairs: /* .. comments .. */ which
may cross multiple lines. C++ introduced a form of comment started by two slashes and
extending to the end of the line: // comment until the line end
The // comment form is so handy that many C compilers now also support it, although it
is not technically part of the C language.
Along with well-chosen function names, comments are an important part of well written code. Comments should not just repeat what the code says. Comments should describe what the code accomplishes which is much more interesting than a translation of what
each statement does. Comments should also narrate what is tricky or non-obvious about a section of code.
