hi.


I am translating C into another language which does not implement pointers.


Has anyone done any work on understanding what a particular pointer does.
Does anyone have an algorithm for eliminating or replacing pointers in C
code?


I know that in general this is very difficult to do but perhaps for
specific cases a solution may exist (i.e. recognizing when pointers are
only being used as call by reference)


Any suggestions or "pointers" will be appreciated.


example pointer elimination:


{
  int x,y;
  int *p; int *q;


  p = &x;
  q = &y;


  *p = *q + 1;
}


can be translated to x = y + 1;


thanks, karen
