Help parsing text file

[dudeomanodude]

Hi all,

I'm trying to parse a text file like this:

i:-15 # Comment Line 1

u:30 # Commnet Line 2

d:5/2009 # Comment Line 3

$:154.72 # Comment Line 4

where the first char is the type, the number or date is some primitive or object, and obviously everything follwoing the '#' is a comment

I'm using this method right now:

parseFile( ifstream& if, Part& p, string fileName ){

  // ommitting the obvious stuff here...

  string temp;
  char type;
  while( getline( if, temp, ':' ){

    // Declare temp primitives and objects here:
    int tempInt;
    unsigned int tempUint;
    // etc...

    switch ( type ){

      case 'i' :

        getline( if, intString, '#' );
        intStream << intString;
        if( !( intStream >> tempInt ).fail() ){

          p.setInt( tempInt );
        }

         // etc

Problem is, if there's more than one int, or whatever in Part p, it overwrites the tempInt or whatever ( respectively ).

This needs to be a very general solution. I know I can't update some Part p within the function the way I have it right now. I just need a fresh idea or an extra set of eyeballs on how to do this.

Any ideas are most appreciated.

Thank you

EDIT:

for clarity, suppose Part looks like this:

class Part{

  public:

    // ...

  private:

   int firstInt;
   int secondInt;
};

case 'i' in the switch can't handle both of these like this. I need to somehow set things up so that the file parser can return a specific type.
