From cppreference.com
< cpp | numeric | random | subtract with carry engine
| void seed( result_type value = 0u ); |
(1) | (since C++11) |
template< class SeedSeq > void seed( SeedSeq& seq ); |
(2) | (since C++11) |
Sets the state of the random-number engine.
Parameters
| value | - | seed value to use to set the state |
| seq | - | seed sequence to use to set the state |
Exceptions
Complexity
1) Same as std::subtract_with_carry_engine(value).
2) Same as std::subtract_with_carry_engine(seq).
