They obscure code and impede its understandability, complicating maintenance. +2. These conversions bypass valuable compiler support, erasing warnings related + to pointer alignment. It may violate strict aliasing rule and leading to + undefined behavior. +3. In scenarios involving multiple inheritance, ambiguity and unexpected outcomes + can arise due to the loss of type information, posing runtime issues. + +In summary, avoiding two-step type conversions through void* ensures clearer code, +maintains essential compiler warnings, and prevents ambiguity and potential runtime +errors, particularly in complex inheritance scenarios. + +Examples: + +.. code-block:: c++ ---------------- PiotrZSL wrote:
