Is there a better way of writing v = (v == 0 ? 1 : 0); [closed]

by

You can simply use:

v = 1 - v;

This of course assumes that the variable is initialised properly, i.e. that it only has the value 0 or 1.

Another method that is shorter but uses a less common operator:

v ^= 1;

Edit:

To be clear; I never approached this question as code golf, just to find a short way of doing the task without using any obscuring tricks like side effects of operators.
