Error handling and resource acquisition

In our experience, exceptions are being used in many different ways in different C++ code bases. (To be fair, this also applies to other languages which supports exceptions.) One reason is that distinct applications can have vastly different requirements when dealing with runtime errors. With some applications, such as a pacemaker or a power plant control system, which may have a severe impact if they crash, we may have to deal with every possible exceptional circumstance, such as running out of memory, and keep the application in a running state. Some applications even completely stay away from using the heap memory as the heap introduces an uncontrollable uncertainty as mechanics of allocating new ...
