Question

C++error C2227: “->link”的左边必须指向类/结构/联合/泛型类型

我想展示无头节点单循环链表
template<typename T>
void circList<T>::output()
{
int i = 0;
CircLinkNode<T>* current = first;
while (current!=NULL&*t->link!=first)
{
cout << "#"<< i<<":" << current->data << endl;
current = current->link;
i++;
}
cout << "#" << i << ":" << current->data << endl;
}

Answer 1

while (current!=NULL&*t->link!=first)
修改成
while (current!=NULL && t->link!=first)

Answer 2

(current!=NULL&*t->link!=first)

NULL后面的&应该是&&吧？*t是什么？t似乎没有在这里出现
