class std::discrete_distribution< _IntType >

A discrete_distribution random number distribution.

This distribution produces random numbers ![$ i, 0 \leq i < n ](https://gcc.gnu.org/onlinedocs/libstdc++/latest−doxygen/form28.png),distributedaccordingtotheprobabilitymassfunction!, distributed according to the probability mass function ![](https://gcc.gnu.org/onlinedocs/libstdc++/latestdoxygen/form28.png),distributedaccordingtotheprobabilitymassfunction! p(i | p_0, ..., p_{n-1}) = p_i $.

Extracts a discrete_distribution random number distribution __x from the input stream __is.

Parameters

__is An input stream.
__x A discrete_distribution random number generator engine.

Returns

The input stream with __x extracted or in an error state.
