How to check two conditions?

How can I check two conditions in if and elseif statment? When I run the following code, I got the last sentence " Your input is negative and even number "

  function output=even_or_odd(n)
 n = 'Insert a number: ';
  x = input(n);
 if x>=0 & rem(n,2)==0
     disp('Your input is positive and even number ');
 elseif x>=0 & rem(n,2)~=0
       disp('Your input is positive and odd number ');
     
 elseif x<0 & rem(n,2)==0
      
     disp('Your input is negative and even number ');
 else
     disp('Your input is negative and even number ');
 end
  end

function output=even_or_odd()
x = input('Insert a number: ');
if mod(x,2)==0&&x>=0
     output='Your input is positive and even number';
elseif mod(x,2)==1&&x>=0
     output='Your input is positive and odd number';
elseif mod(x,2)==0&&x<0
     output='Your input is negative and even number';
else
     output='Your input is negative and odd number';
end
end

Thank you so much. I tried to use && insted of & but I got an error .

% Operands to the || and && operators must be convertible to logical scalar values

I just have question. is it wrong to write x<=0 before rem(x,2)==0?

[David Hill]

No, either way

@Omar B. You'll get that error if you use && or || on non-scalars (i.e., vectors, matrices). Is your code supposed to work for non-scalar inputs or just scalars?

[Omar B.]

I am working with just scalars. In my code I used & not &&.

Thank you so much. I got it.
