Bt $C_n$ you mean the cycle with $n$ vertices, right?
A cycle on $n$ vertices has $2n$ Euler circuits: Each circuit is uniquely determined by the starting vertex ($n$ choices) and then the direction (2 choices).
Each Hamiltonian path is also uniquely determined by the starting vertex $n$ choices and then the direction 2 choices. So there are $2n$ Hamiltonian paths.
Each Hamiltonian cycle is also uniquely determined by the starting vertex $n$ choices and then the direction 2 choices. So there are $2n$ Hamiltonian cycles.
So to answer your question in short, yes there are $2n$ Eulerian circuits, no there are only $2n$ Hamiltonian paths.
