Then inserts each character from the resulting sequenceseq (the contents ofstr plus padding) to the output streamos as if by callingos.rdbuf()->sputn(seq, n), wheren isstd::max(os.width(), str.size())Finally, callsos.width(0) to cancel the effects ofstd::setw, if any.

• N characters are read, whereN isis.width() ifis.width()>0, otherwiseN isstr.max_size(),
• the end-of-file condition occurs in the streamis, or
• std::isspace(c, is.getloc()) istrue for the next characterc inis (this whitespace character remains in the input stream).

If no characters are extracted thenstd::ios::failbit is set onis, which may throwstd::ios_base::failure.

#include <iostream>#include <sstream>#include <string> int main(){std::string greeting="Hello, whirled!";std::istringstream iss(greeting); std::string hello_comma, whirled, word;     iss>> hello_comma;    iss>> whirled; std::cout<< greeting<<'\n'<< hello_comma<<'\n'<< whirled<<'\n'; // Reset the stream    iss.clear();    iss.seekg(0); while(iss>> word)std::cout<<'+'<< word<<'\n';}

Output:

Hello, whirled!Hello,whirled!+Hello,+whirled!
