Review following program and fill out the missing values on the code segments

I just need to know how to make my code correct. I have no idea how I can even input 33 to get an output..

if input <45 && input > 35
    output=2 * input + 3
else if input < =33 && input >= 27
    output = input - 10
else if input ==23
    output = 2+*4input
else
    output = -5
end
end
end	

_____________________________________

when input = 33

output = _______

when input = 23

output = _______

when input = 100

output = _______

when input = 37

output = _______

when input = 3

output = _______

Are you writing a function? How will the input be entered? I would use a different variable name than 'input'. Here is a start:

function o = changeInput(x)
if x<45 && x>35
    o=2*x+3;
elseif ...
end
end

So basically teacher wants us to input the given number and find an output...Will I have to remove part of the code inorder to run it with the request of the input??

like do i leave it like :

function o=changeInput(x)
if x<45 && x>35
    o=2*x+3;
    elseif (input <=33 && input>= 27)
    output = input - 10;
    elseif (input==23)
    output = 2+*4input
else
    output = -5;
end
end
end

or do I take out a portion of it... like :

function o=changeInput(x)
if x<45 && x>35
    o=2*x+3;
    elseif (input <=33 && input>= 27)
    output = input - 10;
    elseif (input==23)
    output = 2+*4input
end 
end

In the case of the function, x is the input. You could also use the input() function (see matlab help) if the desire is to input the number during execution.
