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 [0n), 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]
  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).
