subtract_with_carry_engine() : subtract_with_carry_engine(default_seed) {}	(1)	(since C++11)
explicit subtract_with_carry_engine( result_type value );	(2)	(since C++11)

subtract_with_carry_engine( const subtract_with_carry_engine& );	(4)	(since C++11) (implicitly declared)

Constructs the pseudo-random number engine.

1) Default constructor. Seeds the engine with default_seed.

The overload (3) only participates in overload resolution if Sseq qualifies as a SeedSequence. In particular, it is excluded from the set of candidate functions if Sseq is convertible to result_type.

Parameters

value	-	seed value to use in the initialization of the internal state
s	-	seed sequence to use in the initialization of the internal state

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
P0935R0	C++11	default constructor was explicit	made implicit
