Explanation:
++*p++ ko ham aise execue karenge.
*p pointer ki current location ki value ko define kar rha hai.
++*p currnet location ki value increment ho jaaegi
iat last pointer ki location increment hogi, that is p++ will be executed

ab sabse pehle pointer h ko point kar rha hai. ab sabse pehle uski value mein increment hoga
then uski location mein...to h se i ho jaegaa and ab pointer "a " ko point karne lagega
aise hi last mein pointer null ko point karega. so p1 points to null.
