- When reading about various operators used by programming languages, the term "short circuit behavior" is often used. For example in this C code:
int a = 1;- a && b++
- Someone explained that `b++` is never executed because the logical AND operator "short circuits". What do they even mean with this?
- Assuming I'm a layman at electronics (but not necessarily at programming), the association I get when hearing "short circuit" is something like connecting + directly to - on a battery, resulting in a spectacular failure such as cables burning up. And that doesn't seem like something I would want to happen to my program...
- Why is it called "short circuit behavior"? What's the analogy and how is it helpful in understanding how certain operators work?

What is the meaning of "short circuit" operators?
