int_type sbumpc();	(1)
void stossc();	(2)	(deprecated in C++98) (removed in C++17)

Reads one character and advances the input sequence by one character.

1) If the input sequence read position is not available, returns uflow(). Otherwise returns Traits::to_int_type(*gptr().

2) Same as (1), but discards the result.

Parameters

(none)

Return value

1) The value of the character pointed to by the get pointer, or Traits::eof() if the read position is not available.

Example

See also

sgetc	reads one character from the input sequence without advancing the sequence (public member function)
snextc	advances the input sequence, then reads one character without advancing again (public member function)
