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

A good compiler, such as the Intel C++ compiler, should be able to spot 99% of cases of undefined behaviour. You'll need to investigate the flags and switches to use. As ever, read the manual.
