u hv answered ur ques in ur ques itself...:)
c u understand size of struct node as 4+4=8 rite?? now in this 4 is size of
int and 4 is the size of the pointer of the type struct node...
now wat are p and q? dey are also pointers to struct node jst like
link...now whn u understand dat the size of link is 4 thn u shudnt have any
trouble understanding p and q as well...
I hope im clear..:)
