Master C++ exceptions — try/catch, throw, standard exception types, custom exceptions, stack unwinding, RAII, noexcept, exception safety guarantees with examples.

Master C++ multiple inheritance, the diamond problem, virtual inheritance, mixins, and interface patterns. Learn when to use MI vs composition with examples.

Master C++ abstract classes and interfaces. Learn pure virtual functions, interface pattern, dependency injection, Strategy pattern, Observer pattern, and mock testing.

Master C++ virtual functions and runtime polymorphism. Learn vtable, override, final, virtual destructors, polymorphic containers, RTTI, and plugin architecture patterns.

Master C++ inheritance — base and derived classes, access specifiers, constructors, overriding, object slicing, inheritance vs composition with practical examples.

Master C++ friend functions, friend classes, static member variables, static methods, singleton pattern, and factory methods with practical examples.

Master C++ copy constructors, move semantics, and the Rule of Three/Five/Zero. Learn shallow vs deep copy, move constructor, copy-and-swap idiom with practical examples.

Learn C++ enumerations — old-style enum vs modern enum class, underlying types, switch statements, bit flags, state machines, and best practices with practical examples.
