istreambuf_iterator::operator++

傳回輸入資料流的下一個字元或在加入之前複製物件並傳回複本。

istreambuf_iterator<CharType, Traits>& operator++( );
istreambuf_iterator<CharType, Traits> operator++( int );

傳回值

istreambuf_iterator 或參考為 istreambuf_iterator。

備註

第一個運算子最後嘗試從關聯的輸入資料流擷取和儲存型別 CharType 物件。 第二個運算子來複製物件，加入物件，然後傳回複本。

範例

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

int main( )
{
   using namespace std;

   cout << "Type string of characters & enter to output it,\n"
      << " with stream buffer iterators,(try: 'I'll be back.')\n"
      << " repeat as many times as desired,\n" 
      << " then keystroke ctrl-Z Enter to exit program: ";
   istreambuf_iterator<char> inpos ( cin );
   istreambuf_iterator<char> endpos;
   ostreambuf_iterator<char> outpos ( cout );
   while ( inpos != endpos )
   {
      *outpos = *inpos;
      ++inpos;   //Increment istreambuf_iterator
      ++outpos;
   }
}

  我會傳回。
