极小堆-Min_heap......
看了一个极大堆的实现，大概明白了，于是心血来潮想写一个极小堆的实现，可是。。。写出来，结果有点尴尬= =！！

（有代码，才说话！）

C/C++ code

template <typename T, class ty_>//Wrong in inheriting class vector<T>struct Min_heap:vector<T>{    typedef vector<T>  me_;    Min_heap(void):me_(){}//Suspected here    bool empty(void) const {return me_::empty();}    int size(void) const {return me_::size();}    //T& operator [](int n){return me_.elem_[n];}    T const& top(void) const {return me_[0];}    void shiftup_min(T* a, int n)    {        for (int p = n/2; p>0 && a[p] > a[n]; p = (n = p)/2)            swap(a[p],a[n]);    }    void shiftdown_min(T* a, int n)    {        for (int p = 1, bc = 2; bc <= n; bc = 2*p)        {            if (bc < n && a[bc] > a[bc+1])                ++bc;            if (a[p] > a[bc])            {                swap(a[p],a[bc]);                p = bc;            }            else                 break;        }    }    void push(T const& v)    {        me_::push_back(v);        T* const a = &me_[0] - 1;        shiftup_min(a,me_::size());    }    void pop(void)    {        int const n = me_::size() - 1;        swap (me_[0], me_[n]);        T* const a = &me_[0] - 1;        shiftdown_min(a, n);        me_::pop_back();    }};

error C2275: 'Min_heap<int,struct Huffman_less>::me_' : illegal use of this type as an expression
while compiling class-template member function 'const int &__thiscall Min_heap<int,struct Huffman_less>::top(void) const'
执行 cl.exe 时出错.

请教各位这是怎么回事。。怀疑有问题的地方我标出来了一个，另外可能还有没标出来的。。= =！
以分数为谢。

[解决办法]

C/C++ code

typedef vector<T>  me_;//这里me_是类型名me_::size();，me_::empty();//这里empty函数肯定不会是static函数me_[0];//这里me_又是当成对象使用的//如果楼主本意是将me_定义为对象的话，可以做如下修改typedef vector<T>  me_; --> vector<T>  me_;me_:: --> me_.
