Technical requirementsWhat is memory ownership?Well-designed memory ownershipPoorly designed memory ownershipExpressing memory ownership in C++Expressing non-ownershipExpressing exclusive ownershipExpressing transfer of exclusive ownershipExpressing shared ownershipOwning objects and viewsResource-owning objectsNon-owning access to resource-owning objectsSummaryQuestionsFurther reading
Technical requirementsSwap and the standard template librarySwap and STL containersNon-member swapSwapping like the standardWhen and why to use swapSwap and exception safetyOther common swap idiomsHow to implement and use swap correctlyImplementing swapUsing swap correctlySummaryQuestions
Technical requirementsResource management in C++Installing the microbenchmark libraryInstalling Google TestCounting resourcesDangers of manual resource managementManual resource management is error-proneResource management and exception safetyThe RAII idiomRAII in a nutshellRAII for other resourcesReleasing earlyCareful implementation of Resource Acquisition is Initialization objectsDownsides of RAIIVery modern RAIISummaryQuestionsFurther reading
Technical requirementsWhat is type erasure?Type erasure by exampleFrom example to generalizationType erasure as a design patternType erasure as an implementation techniqueHow is type erasure implemented in C++?Very old type erasureType erasure using inheritanceType erasure without memory allocationType erasure without inheritanceEfficient type erasurePerformance of type erasureInstalling the micro-benchmark libraryThe overhead of type erasureGuidelines for using type erasureSummaryQuestions

Technical requirementsOverload resolution and overload setsC++ function overloadingTemplate functionsType substitution in template functionsType deduction and substitutionSubstitution failureSubstitution Failure Is Not An ErrorWhen substitution failure is still an errorWhere and why does substitution failure happen?Concepts and constraints in C++20Constraints in C++20Concepts in C++20Concepts and type restrictionsSFINAE techniquesSFINAE in C++20SFINAE and type traitsConcepts before conceptsConstrained templates – the best practicesSummaryQuestions
Technical requirementsWhat is wrong with a virtual function?Introducing CRTPCRTP and static polymorphismCompile-time polymorphismThe compile-time pure virtual functionDestructors and polymorphic deletionCRTP and access controlCRTP as a delegation patternExpanding the interfaceCRTP and conceptsCRTP as an implementation techniqueCRTP for code reuseCRTP for generic interfacesCRTP and policy-based designSummaryQuestions
Technical requirementsWhat’s wrong with many arguments?Aggregate parametersNamed arguments in C++Method chainingMethod chaining and named argumentsPerformance of the named arguments idiomGeneral method chainingMethod chaining versus method cascadingGeneral method chainingMethod chaining in class hierarchiesThe Builder patternBasics of the Builder patternThe fluent BuilderThe implicit builderSummaryQuestions
