I've already a circuit that I want to display its output on 7-segment displays, but simply using four switches (to write a 4-bit number) I want to display it on two 7-segment displays,How?
thanks in advance.

Select a display driver that translates a four bit input to a 7 segment drive. Apply you four switches plus pullup resistors to the decoder's inputs. A CD4511 or a 74XX47 will work. Get the data sheet for the IC.
