title: Incrementing in C++ - When to use x++ or ++x?
body: <p>I'm currently learning C++ and I've learned about the incrementation a while ago.
  I know that you can use "++x" to make the incrementation before and "x++" to do it after.</p>
  
  <p>Still, I really don't know when to use either of the two... I've never really used "++x" and things always worked fine so far - so, when should I use it?</p>
  
  <p>Example: In a for loop, when is it preferable to use "++x"?</p>
  
  <p>Also, could someone explain exactly how the different incrementations (or decrementations) work? I would really appreciate it.</p>
