C++11: Variadic Templates

Variadic Parameters were added to Templates.

#include <iostream>

template<class ... Ts>
void f(Ts ... args)
{
  const int size = sizeof...(args) + 1;
  int res[size] = {1, args...};

  std::cout << "------" << std::endl;
  for (int i = 1; i < size; i++)
  {
    std::cout << res[i] << std::endl;
  }
}

int main()
{
  f();
  f(1);
  f(1, 2);
  f(1, 2, 3);
  return 0;
}
/* Output:
