c ++，eclipse，field无法解析

Question

我正在使用eclipse在cpp中实现模板二叉树，我遇到了麻烦。

template <class T> struct node{
    T data;
    struct node *left;
    struct node *rigth;
};
template<class T> node* newnode(T d) {
    struct node *ret = new(struct node());
    ret->left = NULL; //err here
    ret->right = NULL;//err here
    ret->data = d; //err here
    return ret;
}

我收到错误“Field'left'无法解决。”怎么了？提前谢谢。

Answer 1

template <class T> struct node{
    T data;
    struct node<T> *left;
    struct node<T> *rigth;
};

template<class T> node<T>* newnode(T d) {
    struct node<T> *ret = new struct node<T>();
    ret->left = NULL;
    ret->right = NULL;
    ret->data = d;
    return ret;
}
