title: How exactly do pointers in Fortran differ from C/C++ pointers?
body: <p>It might be useful to have both C/C++ programmers and Fortran programmers compare and contrast pointers in these two languages. </p>
  
  <p>In trying to explain to C/C++ programmers how Fortran pointers differ, I usually say pointers to functions or subroutines do not exist. I then try to make the argument that Fortran pointers are more "higher-level", but the details are fuzzy. </p>
  
  <p>What exactly is the difference? </p>
