How to spot undefined behavior

Question

Is there any way to know if you program has undefined behavior in C++ (or even C), short of memorizing the entire spec?

The reason I ask is that I\'ve noticed a lot

Answer 1

I'm not aware of any software tool to detect all forms of UB. Obviously using your compiler's warnings and possibly lint or another static code checker can help a lot.

The other thing that helps a lot is simply experience: The more you program the language, the more you'll see constructs that appear suspect and be able to catch them earlier in the process.
