c++对象指针问题

#include<iostream>
using namespace std;
class B
{
public:
    B()
    {
        length=1; width=1; height=1;
        cout<<"B constructor is executed!"<<endl;
    }
    void show()
    {
        cout<<"length:"<<length<<endl;
        cout<<"width:"<<width<<endl;
        cout<<"height"<<height<<endl;
    }
    ~B()
    {
        cout<<"asdjoasdj"<<endl;
    }
private:
    float length,width,height;
};

int main()
{
    B b;
    B * p=&b;
    cout<<(*p).show()<<endl;
    return 0;
}

提示    cout<<(*p).show()<<endl;  这句有问题    no match for 'operator<<' in 'std::cout << p->B::show()'

xiuos

int main()
{
    B b;
    B * p=&b;
    (*p).show();
    return 0;
}
