sir,this is my code...

module readwrite1;
reg [0:3]reg1[7:0];
integer fp,status;

initial
begin
fp = $fopen ("img.txt","r");
status = $fread (reg1,fp);
end

endmodule


here, file "img.txt" contain integer
1
4
3
5

but our output is(reg1)

reg1(0) 0001
(1) 1010
(2) 0100
(3) 1010
(4) 0011
(5) 1010
(6) 0101
(7) xxxx

what is the reason for getting 1010 at reg1(1,3,5..) ???
how can i read that data in correct format ??

Because you print it as binary in the code that you don't show obviously.

I suggest you read the fine manual for the following two functions:
$fread
$display

For a few $display examples: https://www.asic-world.com/verilog/operators1.html

See the last link I gave you. There are some $display examples that you can just about copy verbatim into your code. Some initiative of your own required.
