I need some help regarding macro expansion in "C".
I'm attempting to have a macro expand into 2 statements
however I get into trouble with a mismatched ";" when
expanding into if/else statements. I would like to have it
compile correctly in both the if/else statements below.

Any ideas would be appreciated.

Thanks,

Ken



#define PIN_LED    4
#define PIN_BUZZER 5

//macro with problem
#define myproblem(pin)  j += pin; i += pin

void main()
{

  int i = 0;
  int j = 0;


   if ( i == j)
         myproblem(PIN_BUZZER);  //bad - compiler sees 2 ; - else not
matched with if
   else
         myproblem(PIN_LED);



   if ( i == j)
   {
         myproblem(PIN_BUZZER); //good - compiler sees 2 ; - but within {}
   }
   else
   {
         myproblem(PIN_LED);
   }


}
