Back to Basics: Object-Oriented Programming in C++
Talkat CppCon 2024 · on Friday, 2024-09-20· at 09:00· Cottonwood 8/9, 6700 North Gaylord Rockies Boulevard·
summary
Shows concrete code and compiler-transformation evidence: uses C++ Insights demo to emit C translation, exposes vtable/vptr reveal and exactly how virtual calls get indexed. Verifies that default parameters are substituted at compile sites so a default-parameter pitfall with virtual functions produces surprising behavior. Demonstrates object slicing, when to make destructors virtual or protected, and claims that a virtual destructor disables move operations. Provides specific examples and slide-linked code (works as shown).
