struct point
{
int x;
int y;
};
struct point origin,*pp;
main()
{
pp=&origin;
printf("origin is(%d%d)\n",(*pp).x,(*pp).y);
printf("origin is (%d%d)\n",pp->x,pp->y);
}


Answer:
origin is(0,0)
origin is(0,0)


Explanation:
pp is a pointer to structure. we can access the elements of the structure either with arrow mark or with indirection operator.

Note:
Since structure point is globally declared x & y are initialized as zeroes
