josephus problem

[DANNY123]

here is my code,the main problem is that there is no problem in the compiler but when you input the first number, you can't put another number.
I am very curious about where did I write wrong.

#include <iostream>
#include <cstdlib>
using namespace std;
template<typename T>
class linklist
{
public:
struct node
{
T data;
struct node*pointer,*next,*t;
};
node*creatnode();
T surviver(int T)const;
};
void f(int)
{}
template<typename T>
typename linklist<T>::node*linklist<T>::creatnode()
{
node*pointer=(struct node*)malloc(sizeof(pointer));//initiate 
cout<<"please input a number,and end with a number 0"<<endl;
T key;
cin>>key;
while(key!=0)
pointer->data=key;
pointer->next=creatnode();
return pointer;

};

template<typename T>
T linklist<T>::surviver(int N)const//find the last node
{
node*t=new node;
int i;
while(t!=t->next)
{
for(i=1;i<N;i++)
t=t->next;
}

cout<<t->data<<endl;
}

int main()
{
linklist<int>josephuslist;
josephuslist.creatnode();
josephuslist.surviver(5);
system("pause");
return 0;
}
