共用方式為


istream_iterator::operator->

傳回成員的值,則為,如果其中任何一個。

const Type* operator->( ) const;

傳回值

成員的值,則為,如果其中任何一個。

備註

- >相當於 (*i) .m

運算子會傳回 &**this

範例

// istream_iterator_operator_vm.cpp
// compile with: /EHsc
#include <iterator>
#include <iostream>
#include <complex>

using namespace std;

int main( )
{
   cout << "Enter complex numbers separated by spaces & then\n"
        << " a character pair ( try example: '(1,2) (3,4) (a,b)' ): ";

   // istream_iterator from stream cin
   istream_iterator< complex<double> > intRead ( cin );

   // End-of-stream iterator
   istream_iterator<complex<double> > EOFintRead;

   while ( intRead != EOFintRead )
   {
      cout << "Reading the real part: " << intRead ->real( ) << endl;
      cout << "Reading the imaginary part: " << intRead ->imag( ) << endl;
      ++intRead;
   }
   cout << endl;
}
  (1,2) 到 (3,4) (a, b)
