insert_iterator<Container> operator++( int );

参数

解决值可以存储的位置的 insert_iterator。

备注

preincrementation 和 postincrementation 运算符返回相同的结果。

示例

// insert_iterator_op_incr.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>

int main( )
{
   using namespace std;
   int i;

   vector<int> vec;
   for (i = 1 ; i < 5 ; ++i ) 
   {
      vec.push_back (  i );
   }
   
   vector <int>::iterator vIter;
   cout << "The vector vec is:\n ( ";
   for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++ )
      cout << *vIter << " ";
   cout << ")." << endl;

   insert_iterator<vector<int> > ii ( vec, vec.begin ( ) );
   *ii = 30;
   ii++;
   *ii = 40;
   ii++;
   *ii = 50;

   cout << "After the insertions, the vector vec becomes:\n ( ";
   for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++ )
      cout << *vIter << " ";
   cout << ")." << endl;
}
