Random number generator (device): Difference between revisions

}</lang>

== {{header|C++}} ==

<code>std::random_device</code> is a uniformly-distributed integer random number generator that produces non-deterministic random numbers.

Note that <code>std::random_device</code> may be implemented in terms of a pseudo-random number engine if a non-deterministic source (e.g. a hardware device) is not available to the implementation.

See the C++ section on [[Random_number_generator_(included)#C.2B.2B|Random number generator (included)]] for the list of pseudo-random number engines available.
