istreambuf_iterator::operator++
Either returns the next character from the input stream or copies the object before incrementing it and returns the copy.
istreambuf_iterator<CharType, Traits>& operator++( );
istreambuf_iterator<CharType, Traits> operator++( int );
Return Value
An istreambuf_iterator or a reference to an istreambuf_iterator.
Remarks
The first operator eventually attempts to extract and store an object of type CharType from the associated input stream. The second operator makes a copy of the object, increments the object, and then returns the copy.
Example
// 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;
}
}
I'll be back.I'll be back.Type string of characters & enter to output it, with stream buffer iterators,(try: 'I'll be back.') repeat as many times as desired, then keystroke ctrl-Z Enter to exit program: I'll be back. I'll be back. ^Z
