if x = 3 and z is unassigned,
why does z = x-- - --x evaluates to 2?
my professor is lecturing about this at the moment, and I’m currently stuck with this dilemma. Unfortunately, no one can explain why it happens.
on x–, x = 3, and after that it’s 2.
on –x, x = 1, because substraction (from 2) is done beforehand.
Therefore, 3 – 1 = 2.
