#include <iostream>
#include <string.h>
#include <stdlib.h>

using namespace std;

template <class C>
struct Node
{
    C  name;
    C number;
    Node<C> *next;

};
template <class C>
class croom
{
    public :
    croom();
    private :
     Node <C> *first;
     Node <C> *p,*s;
};
template <class C>
croom<C>::croom()
{
    int n;
    C name1,number1;
     cout<<"请输入总教室数";
     cin>>n;
     cin.ignore(cin.rdbuf()->in_avail());
     p=NULL;
     for(int i=1;i<=n;i++)
     {
         s=new Node<C>;
         cout<<"请输入教学楼名称";
         //fflush(stdin);
         cin>>name1;
         cin.ignore(cin.rdbuf()->in_avail());
         cout<<endl;

         cin.ignore(cin.rdbuf()->in_avail());
         cout<<endl;
         s->number=number1;
         s->next=NULL;
         //头节点直接插入。
         if(p){
                p->next=s;
                p=p->next;
         }
         else
         {
             first=s;
             p=s;
         }
