What is the error in this code?

#1

I had some problem with IDE on Firefox so I have copied the code directly over here.
The code is giving the error of SIGSEGV.

node* kappend(node* head, int k)
{

node* ntail;
node* nhead;

node* ptr = head;
int count = 0;

while (ptr != NULL)
{

    if (count == k - 1)
    {
        ntail = ptr;
    }
    if (count == k)
    {
        nhead = ptr;
        break;
    }
    ptr = ptr->next;

    count++;

}

node* end = head;

while (end->next != NULL)
{
    end = end->next;
}
ntail->next=NULL;
end->next = head; 


return nhead;

}
