In reply to mlsxdx:

A static variable is global. If you do not want that behavior, then do not use a static variable. You need to change your code to

int get_miles(const int *miles) {
   *miles = *miles + 1;
   return *miles;
}

void runner1() {
   int i, miles;
   for(i=0;i<5;i++) {
      printf("runner1 runs %0d miles\n", get_miles(&miles));
   }
}

void runner2() {
   int j, miles;
   for(j=0;j<5;j++) {
      printf("runner2 runs %0d miles\n", get_miles(&miles));
   }
}
