title: Parameters class in c++
body: <p>I  have a c++ project which has multiple cpp files and functions.</p>
  
  <p>Each file needs its own parameters (i.e., MaxHorizonVelocity, MaxVerticalVelocity etc.). </p>
  
  <p>I want that these parameters <strong>won't be</strong> hard coded but read from a single configuration-parameters file at an initialization step.</p>
  
  <p>For now I think to define a parameters class which will read the parameters at the begining and will be "static" (in some sense which I'm not sure about ...).  </p>
  
  <p>Is that considered a good practice? Is there another way? </p>
