c++ random number

#include <random>

typedef std::mt19937 MyRNG;  // the Mersenne Twister with a popular choice of parameters
uint32_t seed_val;           // populate somehow

MyRNG rng;                   // e.g. keep one global instance (per thread)

void initialize()
{
  rng.seed(seed_val);
}

int main() {
	std::uniform_int_distribution<uint32_t> uint_dist;         // by default range [0, MAX]
	std::uniform_int_distribution<uint32_t> uint_dist10(0,10); // range [0,10]
	std::normal_distribution<double> normal_dist(mean, stddeviation);  // N(mean, stddeviation)
  
  	while (true){
		std::cout << uint_dist(rng) << " "
            	<< uint_dist10(rng) << " "
            	<< normal_dist(rng) << std::endl;
