title: How many and which are the uses of "const" in C++?
body: <p>As a novice C++ programmer there are some constructs that look still very obscure to me, one of these is <code>const</code>. You can use it in so many places and with so many different effects that is nearly impossible for a beginner to come out alive. Will some C++ guru explain once forever the various uses and whether and/or why not to use them?</p>
