C++: Unexpected Behaviour
summary
Lists concrete surprises: code snippets that let private method execute via base pointer, array indexing with literal first (5[a]), overload-resolution gotchas that hide base overloads and require using base::f, optimizer-driven changes where undefined behavior removes or alters code (uninitialized function pointer, signed overflow, redundant reads). Includes fixes (string literal s, wrapper lambdas, static_casts), compiler warnings and static analysis guidance, and slides with full examples and runnable snippets.
