when I simulate my program, and when it executes the part where there is a
cycling light to the right, it shows weird phenomenon

it shows
'10000000' '11000000' '01100000' '00110000' '00011000' '00001100'
 '00000110' '00000011'

and then it works fine
'10000000' '01000000' '00100000'
'00010000' '00001000' '00000100' '00000010' '00000001'

how do i fix this?
I think that there is something wrong with C......maybe
