Antti_M :
Is there any case, where missing a #include
would break the software at runtime, while the build still goes through?
In other words, is it possible that
#include "some/code.h"
complexLogic();
cleverAlgorithms();
and
complexLogic();
cleverAlgorithms();
would both build successfully, but behave differently?
john :
Yes, it's perfectly possible. I'm sure there are lots of ways, but suppose the include file contained a global variable definition which called a constructor. In the first case the constructor would execute, and in the second it wouldn't.
Putting a global variable definition in a header file is poor style, but it's possible.
