I have the following line of code:
temp[fowardI] = temp[fowardI] + temp[backwardI];
Where temp is a byte array (byte[]). When I try to compile it dmd
gives me this error:
source/hash.d(11,25): Error: cannot implicitly convert
expression `cast(int)temp[fowardI] + cast(int)temp[backwardI]` of
type `int` to `byte`
/usr/bin/dmd failed with exit code 1.
Meaning that the byte type doesn't have a + operator. I know by
experience that the pitfall came from C# (which I also use), and
the absence of the operator was justified because the CLI didn't
support addition between values smaller than an int, and also
byte wasn't enough "numberish" to be used as such, and I should
have used int instead.
But why the D language doesn't implement the operator on byte?
