Your code is correct but there are few mistakes.

  1. your midPoint(head) function return pointer to mid point. So cout<<midPoint(head); will print address of pointer. Thus change it to cout<<midPoint(head)->data;
  2. The input format given is wrong. In your code, you first take n then n node values but in input you just provide values of n node. provide value of n too.
  3. Inside buildlist() function, move cin>>data; above insertattail(head,data);
