random1.cpp

Shows how to use xtd::random::next_bytes method.

#include <xtd/console>
#include <xtd/random>
 
using namespace std;
using namespace xtd;
 
auto main()->int {
  auto bytes1 = vector<unsigned char>(100);
  auto bytes2 = vector<unsigned char>(100);
  auto rnd1 = xtd::random {};
  auto rnd2 = xtd::random {};
  
  rnd1.next_bytes(bytes1);
  rnd2.next_bytes(bytes2);
  
  console::write_line("First Series:");
  for (auto i = 0ul; i < bytes1.size(); i++) {
    console::write("{, 5}", bytes1[i]);
    if ((i + 1) % 10 == 0)
      console::write_line();
  }
  
  console::write_line();
  console::write_line("Second Series:");
  for (auto i = 0ul; i < bytes2.size(); i++) {
    console::write("{, 5}", bytes2[i]);
    if ((i + 1) % 10 == 0)
      console::write_line();
  }
}
