While driving, everyone personally thinks that they are the only good driver on Earth. We find all other drivers violating the rules. Then we start driving defensively. We look out for trouble before it happens. We always expect the unexpected.
The situation is similar in software world. We constantly encounter code written by other programmers - code that might not live up to our high standards. We check for errors or bad data.
But pragmatic programmers are always a step ahead.
They don't trust themselves, either!
No one writes perfect code. There is nothing called perfect software. We all should accept this fact. Pragmatic programmers code in defenses against their own mistakes.
Here, we’ll discuss about the defensive measures we take while coding.
