module comparator ( a ,b ,equal ,greater ,lower );

output equal ;
reg equal ;
output greater ;
reg greater ;
output lower ;
reg lower ;

input [3:0] a ;
wire [3:0] a ;
input [3:0] b ;
wire [3:0] b ;

always @ (a or b) begin
if (a<b) begin
equal = 0;
lower = 1;
greater = 0;
end else if (a==b) begin
equal = 1;
lower = 0;
greater = 0;
end else begin
equal = 0;
lower = 0;
greater = 1;
end
end


endmodule
