What is the output of this code and why?

int main() { int x=1,y=1,z=1; cout<<(++x||++y&&++z); cout<<x<<y<<z; }

It's called Short Circuit Evaluation and is a common way of optimization used by many compilers. It means essentially the compiler will only evaluate what he needs to know in order to know the result of a statement.
