title: How to delete elements of a pointer in c++
body: <p>If I have a pointer <code>float *p;</code> And I want to delete one element of its elements or all of its elements .. Is there any operator can do this??</p>
  
  <p>And <code>delete [] p;</code> operator will delete only the address of the pointer or the elements too?</p>
  
  <p>Thanks in advance.</p>
