merge 算法

[wzyzb]

merge 能不能连接两个容器 比如list<B > t1,t2, B为类名
t1.merge(t2); 编程的时候提示错误

哥们，查一下merge再用

template <class InputIterator1, class InputIterator2, class OutputIterator>
  OutputIterator merge ( InputIterator1 first1, InputIterator1 last1,
                         InputIterator2 first2, InputIterator2 last2,
                         OutputIterator result );

template <class InputIterator1, class InputIterator2,
          class OutputIterator, class Compare>
  OutputIterator merge ( InputIterator1 first1, InputIterator1 last1,
                         InputIterator2 first2, InputIterator2 last2,
                         OutputIterator result, Compare comp );

自己先装个msdn，查了再说。

//merge(t1.begin(),t1.end(),t2.begin(),t2.end(),t3);
for(iter=t1.begin();iter!=t1.end();iter++)

//merge(t1.begin(),t1.end(),t2.begin(),t2.end(),t3);
t3.begin()试试
