As other mentioned, you have two methods to do it in C++,

1, Using template. Unlike the real duck typing, the type is
solved at compile time, not at runtime.
But using template maybe hard to implement OOP hierarchy.

2, Using interface. I think this is how duck typing should
be. If an object looks like a duck, walks like a duck,
even it's not a duck, it must have duck behavior, which
is IDuck.
This is easier to implement OOP hierarchy.
