I want to toggle a variable between 0 and 1. If it’s 0 I want to set it to 1, else if it’s 1 I want to set it to 0.
This is such a fundamental operation that I write so often I’d like to investigate the shortest, clearest possible way of doing it. Here’s my best so far:
v = (v == 0 ? 1 : 0);
Can you improve on this?
Edit: the question is asking how to write the above statement in the fewest characters while retaining clarity – how is this ‘not a real question’? This wasn’t intended to be a code-golf exercise, though some interesting answers have come out of people approaching it as golf – it’s nice to see golf being used in a constructive and thought-provoking manner.
