how to change it?

i =0;

while (i<10)

            i = i+1;

            x = input('enter the number');

            if isreal(x)

                if isinteger(x)

                end

            end

           if (x>255)

    disp('"error:Value too big."')

else if ((x>=0) && (x<=255))

       disp('<x>')

       else

        disp('-1')

    end

           end
end
What's wrong with this script? In command window, it appear the letter <x>. But I want to get the input number of x. Besides, it can only do it 10 times whatever the number I input. I expect it can work during the range 0-255 10 times. How to change it?

Shi, check out

 fileID = fopen('num.txt','w');
 while (i<10)
    x = input('enter the number: ');
    if isreal(x)                     % no action?
        if isinteger(x)              % no action?
        end
    end
    if (x>255)
        disp('"error:Value too big."');
    elseif ((x>=0) && (x<=255))
        disp(['<',num2str(x),'>']);  % display the value of x
        i = i+1;                     % increment i if x in range
        fprintf(fileID,'%d\n',x);
    else
        disp('-1');                  % display string '-1'
    end
 end
 fclose(fileID);

I want to add the <>between my output result. I dong't know what I should say in action.If it is a real number, it should go on the script.Else, it should be rejected. The same to integer. What should I do about it? How to add a file to save all the elements?
