My textbook gave me code that has an error I don't know how to fix

if flag==1 && alt>=30000
fprintf('Normal operation at %0.0f feet.\n',alt)
elseif flag==0 || alt==0
fprintf('On Ground')
elseif flag==2 && alt < 30000
fprintf('Currently at %0.0f feet and climbing\n',alt)
elseif flag==3
fprintf('Currently at %0.0f feet and descending\n',alt)
else
fprintf('Status transitional')
end

Please here is the code!

This is the error I'm getting

Operands to the || and && operators must be convertible

to logical scalar values.

Error in Homework4q5 (line 3)

if flag==1 && alt>=30000

alt and flag must be scalars.

They are, the inputs for alt and flag given are

flag = 1; alt = 25000

flag = 0; alt = 7500
flag = 2; alt = 10000
flag = 1; alt = 37000
flag = 3; alt = 35000

It's not giving me any problems.

flag = 1; alt = 25000;


if flag==1 && alt>=30000
fprintf('Normal operation at %0.0f feet.\n',alt)
elseif flag==0 || alt==0
fprintf('On Ground')
elseif flag==2 && alt < 30000
fprintf('Currently at %0.0f feet and climbing\n',alt)
elseif flag==3
fprintf('Currently at %0.0f feet and descending\n',alt)
else
fprintf('Status transitional')
end

disp ' '

Running this gives me

Status transitional

Thank you I realized what I was doing wrong, I had the flag and alt values after the code. Its been a long day
