void set_counter( const std::array <result_type, n>& c );
(since C++26)
Sets the counter of the random-number engine.
- For each integer k in
[0,n), sets \(\scriptsize X_k \)Xk to \(\scriptsize c_{n-1-k} \mod 2^w \)cn-1-k mod 2w
. - The value of j is set to n - 1.[1]
- ↑ As j is being set to n - 1, the next state transition always generates new random values.
[edit] Parameters
c
-
counter sequence to use to set the counter
[edit] Complexity
\(\scriptsize O(n) \)O(n).
