Question

public void Consumer()
{
    foreach(int i in Integers())
    {
        Console.WriteLine(i.ToString());
    }
}

public IEnumerable<int> Integers()
{
    yield return 1;
    yield return 2;
    yield return 4;
    yield return 8;
    yield return 16;
    yield return 16777216;
}

Is there a way with template trick (or other) to get the same syntax in c++?

Take a look at boost::Coroutine. It does what you want.

Example from tutorial

int range_generator(generator_type::self& self, int min, int max) 
{
     while(min < max)
         self.yield(min++);
     self.exit();
}
