It's not valid C.

Use this instead :

int main(){
  struct xyz {
    int i;
  };
  struct xyz *p, a = { 10 };  /* <-- the correct way to initialize a struct is with {}'s */
                              /* <-- you have to use "struct xyz" instead of just "xyz" */
  p = &a;   /*  <-- don't assign to *p, as you haven't allocated memory for it !! */
  p->i = 10;
  printf("%d", a.i);
  getch();
}

assuming you meant
 struct xyz *p,a={10};
it means
struct xyz a;
a.i=10;

but
 *p=a;
refrerences an uninitialized pointer, which makes the behaviour of the program undefined
