title: Do we need pointers?
body: <p>Is there any case or specific example where we would require pointers for the job?
  i.e. could something that requires pointers be done without using them?
  We could send pointers as a function parameter but that could be done with returned data. We can use pointers to change more than one variable in a function but there is a workaround for that too.</p>
  
  <p>Do we actually need pointers?</p>
  
  <p>I know it is a silly question, sorry,but under the circumstances seems correct to me
  I just want to know if there is something we cannot do using pointers.</p>
