short can't arithmetic with constant?

[sd]

short Total=11;
short Index=Total-1;

will occurs the following error:

error CS0266: Cannot implicitly convert type 'int' to 'short'. An
explicit conversion exists (are you missing a cast?)

and this is correct:

short Index=(short)(Total-1);

A bit ugly...

sd,

11 and 1 are considered integers by the compiler. Trying to place an
integer in a short can result in a possible data loss, hence the compiler
warning.

You can also do this:

short Index = Total - ((short) 1);

And that should work.

Hope this helps.

.... and that's exactly what you have to do. Actually using int would be more
efficient believe it or not.

Nope, the result of the subtraction is an int so you still need the
cast.
