Change that else to
else if(head != null)
Because if there is only one element then pointer_node will still increment and would become null which would give null pointer exception

[mridulchaudhary]

initialize int c = -1 rather than c = 0. Because its showing run time error.

NPE should come, need to add boundary condition in this logic as suggested by Mahesh & Arjun

[ashishdukare]

while(head->next != NULL) isn't this should be there instead of the above code?

[GRMREAPR]

I dont understand how the loop breaks out when we reach position 7 and not just continue traversing?

[elasingh]

I dont understand the logic here. Can anyone please explain?
