Hi
the problem is that the original linked list gets updated on calling the reverse function
even thought the head pointer is passed as value and u do not expect it to be updateed in the int main () function
but this not so because in the reverse function u are updating the pointer of the linked list hence the linked list gets updated permanently

hence head has now been manipulated
if u try printing whats in the linked list with ‘head’ has its head
u`ll recieve the first element only

so
u need to use some other approach
in case u are not able to firgure out
ask in comments below
