++ --

The increment and decrement operators make it possible to write in an extremely terse style. In languages such as C, they made it possible to write one-liners that could do string copies:

for (p = src, q = dest; !*p; p++, q++) *q = *p;```

They also encourage a programming style that, as it turns out, is reckless. Most of the buffer overrun bugs that created terrible security vulnerabilities were due to code like this.

In my own practice, I observed that when I used ++ and --, my code tended to be too tight, too tricky, too cryptic. So, as a matter of discipline, I don’t use them any more.

I think that as a result, my coding style has become cleaner.
