list::merge

從引數清單中移除項目，將它們插入至目標清單，以及排列項目的新，綜合集以遞增順序或按下某個其他指定的順序。

void merge(
   list<Type, Allocator>& _Right
);
template<class Traits>
   void merge(
      list<Type, Allocator>& _Right, 
      Traits _Comp
   );

參數

• _Right
  與目標清單合併的引數清單。

• _Comp
  比較運算子用於排序受目標的項目清單。

備註

引數清單 _Right 與目標清單合併。

必須命令引數和目標清單與這個產生的序列會排程的相同的比較關聯。第 10% 成員函式的預設命令是遞增順序。第二 + 成成員函式加上類別 Traits的使用者指定的比較作業 _Comp 。

範例

// list_merge.cpp
// compile with: /EHsc
#include <list>
#include <iostream>

int main( ) 
{
   using namespace std;
   list <int> c1, c2, c3;
   list <int>::iterator c1_Iter, c2_Iter, c3_Iter;
   
   c1.push_back( 3 );
   c1.push_back( 6 );
   c2.push_back( 2 );
   c2.push_back( 4 );
   c3.push_back( 5 );
   c3.push_back( 1 );

   cout << "c1 =";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;

   cout << "c2 =";
   for ( c2_Iter = c2.begin( ); c2_Iter != c2.end( ); c2_Iter++ )
      cout << " " << *c2_Iter;
   cout << endl;

   c2.merge( c1 );  // Merge c1 into c2 in (default) ascending order
   c2.sort( greater<int>( ) );
   cout << "After merging c1 with c2 and sorting with >: c2 =";
   for ( c2_Iter = c2.begin( ); c2_Iter != c2.end( ); c2_Iter++ )
      cout << " " << *c2_Iter;
   cout << endl;

   cout << "c3 =";
   for ( c3_Iter = c3.begin( ); c3_Iter != c3.end( ); c3_Iter++ )
      cout << " " << *c3_Iter;
   cout << endl;

   c2.merge( c3, greater<int>( ) );
   cout << "After merging c3 with c2 according to the '>' comparison relation: c2 =";
   for ( c2_Iter = c2.begin( ); c2_Iter != c2.end( ); c2_Iter++ )
      cout << " " << *c2_Iter;
   cout << endl;
