It's normal that you get problems from this code, and it has nothing to
do with what you said... in C '*' means pointer. so your function
accepts 2 pointers to ints and returns an int pointer. 
   result=first+second  does not add values, it adds pointers. You could
re-write the function as

 char add(char first, char second)
 {
return(first+second);
 }

or, if you *REALLY* want a pointer returned and 2 pointers passed, do
this: (a lot more complicated tho)

char *add(char *first, char *second)
{
  int *result;
  result=(int*)malloc(sizeof(int));
  (*result)=(*first)+(*second);
  return (result);
}
