Definition of electrodes

Whether an electrode operates as a cathode or anode depends on the direction the cell is operating in. If a cell is switched from operating galvanically (i.e. outputting energy like a battery) to electrolysis (energy is input to the cell) then its cathode will become its anode and vice versa.

I am asking this question to clear my doubt regarding a Daniell cell as to why $ce{Cu}$ rod used in the cell should be positively charged. I don't get it, though $ce{Zn}$ rod dipped in $ce{ZnSO4}$ solution acquires negative charge due to oxidation of $ce{Zn}$ to $ce{Zn^2+}$ is clear to me, but how can $ce{Cu}$ rod dipped in $ce{CuSO4}$ be positively charged.
