basic_istream::putback

Puts a specified character into the stream.

basic_istream<Elem, Tr>& putback(
    char_type _Ch
);

매개 변수

• _Ch
  A character to put back into the stream.

반환 값

The stream (*this).

설명

The unformatted input function puts back _Ch, if possible, as if by calling rdbuf->sputbackc. If rdbuf is a null pointer, or if the call to sputbackc returns traits_type::eof, the function calls setstate(badbit). In any case, it returns *this.

예제
