定义一个杂凑表类

定义一个杂凑表类，要求用数组存放杂凑表元素，以字符串作关键字存放和查找表元素，并提供用于插入、查询和删除杂凑表元素的public函数成员。

    #include<alloc.h>
    Class HASH{
        class NODE{
             int value;
             NODE *next;
           public:
             int getvalue(){return value;}
             NODE *getnext{return next;}
             NODE *setnext(NODE *n){next=n;return this;}
             NODE(int v,NODE *n){value=v;next=n}
            ~NODE(){if(next)delete next;}
            }
            struct BARREL{char *s;NODE *n;}*h;
            int c;
            const int t;
          public:
             HASH(int m);
             NODE *lookup(const char *s,int v);
             int insert(const char *s,int v);
             int remove(const char *s,int v);
             ~HASH();
