Answer:
-------------

   The error line mentioned needs to changed from
  
   scanf("%lf %lf",p->x, p->y);
  
   To
  
   scanf("%lf %lf",&p->x, &p->y);
  
   This will fix the issue.
  
-------------------
Explanation:
-------------------

   In Point structue x and y are of type simple double variables.
   Since all the normal variables are read using '&' symbol using scanf.

Making the p->x to &p->x
   and    p->y to &p->y  

These changes resolve the issue of reading point data from keyboard using scanf.
