#include 
   
    #include 
    
     using namespace std;template 
     
      class CMyistream_iterator{
   // 在此处补充你的代码};int main()  {
    	int t;	cin >> t;	while( t -- ) {
   		 CMyistream_iterator
      
        inputInt(cin);		 int n1,n2,n3;		 n1 = * inputInt; //读入 n1		 int tmp = * inputInt;		 cout << tmp << endl;		 inputInt ++;   		 n2 = * inputInt; //读入 n2		 inputInt ++;		 n3 = * inputInt; //读入 n3		 cout << n1 << " " << n2<< " " << n3 << " ";		 CMyistream_iterator
       
         inputStr(cin);		 string s1,s2;		 s1 = * inputStr;		 inputStr ++;		 s2 = * inputStr;		 cout << s1 << " " << s2 << endl;	}	 return 0;  }
       
      
     
    
   

代码实现

private:    T ret;    bool read;public:    CMyistream_iterator(istream & a){
   read = false;}    T operator*()    {
           if(!read)        {
               cin>>ret;            read = true;        }        return ret;    }    void operator++(int n)    {
           read = false;    }
