verilog code

why cant you write it yourself?

Quartus II has templates for things like these. With your verilog file opened in Quartus go to the edit menu --> templates and find the multiplication template under the verilog templates.

i dont have knowleadge about for loop concept in verilog.

common mistake that people always make when they are moving into programmable logic, they always thought writing RTL codes is similar to writing software codes.

You can find it here: fpga4fun.com though I would recommend you trying to implement it by yourself first.
