Answer 1

++x gives ++0 ie 1
plus
--x gives --1 ie 0
1+0 is 1

Alternatively you can go like this
a=++x. //1
b=--x. //0
Output.. a+b //1+0=1

Most probably it goes like this only..

Answer 2

Keep in mind what @Rrestoring faith said. There is no single way to determine the output, because compilers and compilers differ and may produce different results, even in one language.

Answer 3

Java works with these a little differently from C++ if that's what's causing your confusion. In C++ this code would give 0. In Java, what @Frost said.

Thank you
