istream_iterator::operator++

從輸入資料流中遞增的物件或在將它之前複製物件並傳回複本。

istream_iterator<Type, CharType, Traits, Distance>& operator++( ); 
istream_iterator<Type, CharType, Traits, Distance> operator++( int );

傳回值

第 10% 成員運算子會從輸入資料流傳回在擷取的型別 型別 遞增物件的參考，而第二 + 成成員函式會傳回物件的複本。

範例

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

int main( )
{
   using namespace std;

   cout << "Enter integers separated by spaces & then\n"
        << " a character ( try example: '2 4 6 8 a' ): ";

   // istream_iterator from stream cin
   istream_iterator<int> intRead ( cin );

   // End-of-stream iterator
   istream_iterator<int> EOFintRead;

   while ( intRead != EOFintRead )
   {
      cout << "Reading:  " << *intRead << endl;
      ++intRead;
   }
   cout << endl;
}

  2 4 6 8。
