Definido en el archivo de encabezado <random>
template< class IntType = int >
class uniform_int_distribution;
(desde C++11)

Produce los valores enteros aleatorios i, distribuidos uniformemente en el intervalo cerrado [a, b], es decir, distribuidos de acuerdo con la función de probabilidad discreta

P(i|a,b) =
1
b − a + 1
.

std::uniform_int_distribution satisface todos los requerimientos para RandomNumberDistribution

[editar] Ejemplo

Este programa simula lanzar dados de 6 caras.

#include <random>
#include <iostream>
int main()
{
    std::random_device rd;
    std::mt19937 gen(rd());
    std::uniform_int_distribution<> dis(1, 6);
    for(int n=0; n<10; ++n)
        std::cout << dis(gen) << ' ';
    std::cout << '\n';
}

Posible salida:

1 1 6 5 2 2 5 5 6 2
