编译过了，但不能继续运行下去。

case输出能否进行呢？
具体是到哪一步执行不了？

改了3个较明显的错误，你自己测试一下看看。

 struct User/*电话薄结构*/
{
    char name[8];
    char tel[11];
    char add[20];
    User *next; //修改
}user;

        if (strcmp(name, p->user.name)==0)//去掉一个;分号
        {
            cout << p->user.name << "_" << p->user.add << "_" << p->user.tel << endl;
            break;
        }

        if (strcmp(tel, p->user.tel) == 0)//去掉一个;分号
        {
            cout << p->user.name << "_" << p->user.add << "_" << p->user.tel << endl;
            break;
        }

括号使用错误去掉。

        case 3:
            //{

                Node *p = hashtable1[key1];
