Bueno ya que C++11 es bastante nuevo dejo este ejemplo de generacion de numeros aleatorios:

#include <iostream>
#include <random>
#include <cstdlib>
#include <ctime>
 
int main(int argc, char **argv)
{
 std::mt19937 rng;
 std::srand(time(NULL));
 uint32_t seed = std::rand();
 rng.seed(seed);
 
 uint32_t stats[10] = {0}, current;
 
 std::cout << "*** Random number generation test ***" << std::endl;
 
 std::uniform_int_distribution<uint32_t> uint_dist(0, 10);
 
 for(size_t i=0; i<56000u; i++)
 {
  current = uint_dist(rng); 
  stats[current-1]++;
  std::cout << current << ' ' << std::endl;
 }
 
 std::cout << "*** Number of times for each number ***" << std::endl;
 
 size_t i=1;
 for(auto x : stats)
 {
  std::cout << "$ " << i++ << '\t' << x << std::endl;
 }
 
 std::cout << "*** End of the test ***" << std::endl;
 
 return 0;
}

Los resultados son bastante uniformes
