title: Difference between const. pointer and reference?
body: <p>What is the difference between a constant pointer and a reference? </p>
  
  <p>Constant pointer as the name implies can not be bound again. Same is the case with the reference.</p>
  
  <p>I wonder in what sort of scenarios would one be preferred over the other. How different is their C++ standard and their implementations?</p>
