add Int8 and int16

how can I write a code for this:

By default, it is not possible to add an int8 value to an int16 value. Write a function that accepts an int8 argument and an int16 argument and adds them together, returning the resulting value as an int16 value.

what I started to write:

function out2=add_int(in1,in2)

%Write a function that accepts an int8 argument and an int16

%argument and adds them together, returning the resulting value as an int16 value.

out=int8(in1)+int16(in2);

out2=int16(out);

add_int(int8(127),int16(129))

ans = int16 256

function out = add_int(in1,in2)
out = int16(in1) + int16(in2);
end

it's homework...

Thank you so much for the response @Stephen Cobeldick. yeah it is a homework from my enginnering book on Matlab I try to do as many homework they provide on the book to get better practice. Thank you all for helping me.

Think about what input variables you have, what type they have and which one you need to cast to another data-type.
