c/c++:逆序建立链表

数据结构实验之链表二：逆序建立链表

#include <iostream>
#include <cstring>
using namespace std;
struct node

    int data;
    struct node *next;

    head = new node;

    tail = head;
    int N ;
    int tmpN;
    cin>>N;
    {

            p = new node;
            cin >> p->data ;
            p->next = head->next;
