c++ - 同一集合上的两个不同迭代器是否相等

Question

假设我使用嵌套的 for 来比较同一列表中的对象:

for( list<Object>::iterator iter = list.begin() ; iter != list.end() ; ++iter )
  {
    for( list<Object>::iterator iter2 = list.begin() ; iter2 != list.end() ; ++iter2 )
    {
      if( iter == iter2 )
      {
        // does this mean iter is pointing to the same INDEX
        // as iter2?  Will this work as expected?
      }
    }
  }

Answer 1

是的，这正是您所期望的，并且工作正常。
