34. precedence

The code outputs the following:

2
2
0
2

This is because of the usage of the ++ and -- operators along with the unary + and - operators.

In the first line, a is incremented twice due to the usage of +++ (which is interpreted as a++ + a). This results in 2.

In the second line, b is incremented once due to the usage of + + + (which is interpreted as + (+ (+b))). This also results in 2.

In the third line, c is decremented twice due to the usage of --- (which is interpreted as c-- - c). This results in 0.

In the fourth line, d is decremented once due to the usage of - - - (which is interpreted as - (- (-d))). This results in 2.
