Hello!

I have been programming C++ for quite some time but I havn't used the
standard containers very much.. Right now I'm building a compiler and I have
a problem with using iterators on a map... This code shows my point (and
generates an error with DJGPP)... What is wrong with this code? Shouldn't I
be able to use the * operator to get the contents of the iterator?

Thanks in advance / Niklas Pettersson

#include <string>
#include <map>

struct SymbolTableEntry // Dummy.. Just to illustrate..
{
};

map<string, SymbolTableEntry *> symboltable_rep;

void print()
{
   map<string, SymbolTableEntry *>::iterator i( symboltable_rep.begin() );
   SymbolTableEntry *current = 0;

   while ( i != symboltable_rep.end() ) // end is one past last element
   {
      //
      // ERROR HERE!!!
      //
      current = *i; // Get contents of iterator...

    // Do stuff here with current

      i++;
   }
}
