Question

我正在尝试使用sho来显示另一个函数的输出。第一个函数用于进行排序，并返回一个List。

现在我想创建一个使用show（）来显示输出的函数。这就是我尝试它只是为了得到一个错误。

它用于显示两个使用此函数的两个排序列表的结果。

    //Function that does the compare!

    map<int, Bid*> Auctioneer::compareBidList(map<int, Bid*>& one, map<int, Bid*>& 
                   two) // pass references &
     {
  map<int, Bid*> Sorted;
       map<int, Bid*>::iterator iterOne;
  for(iterOne = one.begin(); iterOne != one.end(); ++iterOne)
 {
    if(iterOne->second->bidType == 'A') // select all type A from one
    {
        map<int, Bid*>::iterator iterTwo;
        for(iterTwo = two.begin(); iterTwo != two.end(); ++iterTwo)
        {
            if(iterTwo->second->bidType == 'B') // select all
         type B from two
            {
                if(iterOne->second->price < iterTwo->second-
                          >price) // select on price between type A and type B
                {
                    Sorted.insert(*iterOne);
                    Sorted.insert(*iterTwo);
                }
            }
        }
    }
   }                
   return Sorted;
   }

 void show(map<int, Bid*>& one, map<int, Bid*>& two) { 
    map<int, Bid*>::iterator iterOne;
    map<int, Bid*>::iterator iterTwo;
   cout << "-----------------The sorted List-------------------------";     
   for(iterOne=Sorted.begin(); iterOne!= Sorted.end(); iterOne++){
   cout << iterOne->second->toString() << endl<<"\n";}
   for(iterTwo=Sorted.begin(); iterTwo!= Sorted.end(); iterTwo){
   cout << iterTwo->second->toString() << endl<<"\n";}  
   }  

 void show(const char *msg, map<int, Bid*>& Sorted) {  
       cout << msg << endl; 
       show(Sorted);
        }  
void compare(map<int, Bid*>& sellers, map<int, Bid*>& buyers) { 
    compare(sellers.begin(), sellers.end(),
    buyers.begin(),buyers.end(),compareBidList); } 

//my call in the main after declaration was as follows
   map<int, Bid*> buyers, sellers;
   auctioneer.compare(sellers,buyers);
   show("Bids after sorting:", sellers); 
   show(buyers);

Answer 1

删除额外的括号，并调用show两次（您的声明只接受一个地图对象）：

show("Bids after sorting:", sellers);
show(buyers);

如何使用show函数生成输出
