chess clock coding using quartus II

OK, so you need first of all a good book of Digital Electronics Design just to understand how a design idea can be translated into a FSM (which can be described conveniently by a state diagram). After that you will need to have a tutorial of Quartus II environment (directly available after installing Quartus II) and then you need to learn HDL programming.

So you can understand that the process is a bit long and not simply solvable through some forum clues.

If you need, I can suggest you some good books for Digital Electronics and for VHDL/Verilog programming

Cheers
