please help with verilog coding

Shifter Implement a 32-bit shifter. Input: x (32 bits), c (5 bits), and op (2 bits). Output: y.

This shifter should shift the input number x by c bits according to the shift operations indicated by op:

op = 0 left logical shift,

op = 1 right logical shift,

op = 2 right arithmetic shift,

and op = 3 left circular shift. For example,

if x=0x80000001 and c=4, the value of y should be 0x00000010 if op=0, 0x08000000 if op=1, 0xF8000000 if op=2, and 0x00000018 if op=3. Notice that you cannot use shift operators in Verilog (including <<, <<<, >>, and >>>) directly in this module.
