I can create a literal long by appending an L to the value; why can't I create a literal short or byte in some similar way? Why do I need to use an int literal with a cast?
And if the answer is "Because there was no short literal in C", then why are there no short literals in C?
This doesn't actually affect my life in any meaningful wa...
