#include <iostream>
class test
{
        public:
            int& get()
                {
                        return *p;//返回的是*p的引用
                }
                int *p;
};

int main()
{
        test te;
        int k=5;
        te.p=&k;
        int i;
       i=te.get();
        std::cout<<i<<std::endl;
