What do you want to learn this week?

This module refreshes how C++ models objects through classes, controls object state, manages construction and copying, and preserves interface guarantees with constness and parameter passing. Learners then trace inheritance and dynamic dispatch while synthesizing object lifetime, copying, and polymorphic behavior.

• ·Classes and Encapsulation

  Review class definitions, data members, member functions, and the distinction between an object's interface and its representation. Trace how public, private, and protected access affect which code can inspect or modify an object's state.

• ·Constructors, Destructors, and Copying

  Reason about when constructors and destructors run and how copying creates or assigns object state. Distinguish copy construction from copy assignment and connect each operation to the lifetime of the objects involved.

• ·Constness and Parameter Passing

  Analyze const objects, const member functions, and const references as guarantees about permitted modification. Compare pass-by-value, pass-by-reference, and pass-by-pointer by tracing aliasing, copying, and whether a function can change the caller's object.

• Inheritance and Dynamic Dispatch

  Synthesize class interfaces, object construction and copying, constness, and parameter passing with inheritance and dynamic dispatch. Analyze base and derived objects through references or pointers, including the role of virtual functions and virtual destructors in safe polymorphic use.

This module refreshes generic programming and the Standard Template Library through focused reasoning about function templates, container capabilities, iterator-based algorithms, and performance trade-offs. Learners progress from reading template code to selecting and evaluating STL data structures in unfamiliar C++ code.

• ·Function Templates

  Function templates define type-independent operations that the compiler specializes for particular arguments. Learners reason about template parameters, deduction, explicit type arguments, and how the resulting types affect overload behavior and expressions.

• ·STL Container Selection

  STL containers provide different guarantees for storage, access, insertion, removal, ordering, and key lookup. Learners compare those guarantees to determine which container fits a stated set of operations.

• ·Iterators and Algorithms

  Iterators provide a common way to traverse ranges, while STL algorithms operate on those ranges without depending on a particular container. Learners reason about half-open ranges, iterator categories, algorithm preconditions, return iterators, and element mutation.

• STL Performance and Data-Structure Choices

  This synthesis assessment combines template reasoning, container selection, iterator-based algorithms, and complexity analysis. Learners diagnose mismatches between required behavior and chosen STL components, then compare alternatives by access, update, lookup, traversal, and invalidation costs.
