The following Verilog code has a number of errors. Find any $3$ additional sources of errors.

Write the line number of the error, provide a reasoning for the error, and propose a fix for the

error.

module errors

input clk$,$

input reset,

input data,

input $p,$

output $r,$

output reg $[3$:$0]$q$)$;

always @$($posedge clk$)$ begin

if $($reset $=1)$ begin

q d$0$;

$r{1}^{\text{'}}b0$;

end

else begin

$q[3]$ data;

$q[2]q[3]$;

$q[1]q[2]$;

$q[0]q[1]$;

assign $r=p$;

end

end

endmodule;
