102: C++23 Fundamentals and Advanced STL. Skills
Upon completing this training, participants will transform into high-caliber systems engineers capable of leveraging the full power of C++23. Graduates will possess the expertise to architect zero-overhead, memory-safe applications using RAII and Smart Pointers, effectively eliminating legacy manual allocation bugs. You will master performance optimization through Move Semantics, gaining the ability to manage resource ownership and eliminate redundant deep copies. Furthermore, trainees will demonstrate deep proficiency in the Standard Template Library (STL), skilled in selecting optimal containers and implementing efficient, declarative algorithms. Ultimately, attendees will emerge ready to design scalable, production-grade software using the latest industry standards.
Upon completing this training, the trainee will possess following skills.
Environment & Modern Core
Toolchain Configuration: Ability to configure and verify C++23 compliant environments using GCC 14, Clang 17, or MSVC v17.6+.Modular Architecture: Competence in replacing header files (#include) with C++23 Modules (import std;) for faster compilation and better isolation.Modern I/O Formatting: Proficiency in using type-safe I/O with std::print and std::println, discarding legacy printf or verbose stream operators.Advanced Type Deduction: Mastery of auto and decltype to write cleaner, refactor-resistant code without losing type safety.Structured Data Handling: Ability to use Structured Bindings to unpack tuples, pairs, and structs directly into readable variables.Uniform Initialization: Skill in using brace initialization {} to prevent narrowing conversions and ensure consistent object creation.
Memory Management & Safety (RAII)
RAII Enforcement: The ability to architect classes where resource lifecycle is tied strictly to object scope, eliminating resource leaks.
Zero-Allocation Policy: The discipline to write complex applications without a single manual new or delete.Exclusive Ownership Models: Mastery of std::unique_ptr for creating clear, owner-centric object hierarchies with zero overhead.Shared State Management: Competence in using std::shared_ptr for safe resource sharing across multiple owners using reference counting.Cycle Breaking: Ability to identify memory leaks caused by circular references and resolve them using std::weak_ptr.Custom Deleters: Skill in wrapping legacy C-APIs (like file handles or sockets) inside smart pointers with custom cleanup logic.
Move Semantics & Optimization
Value Category Analysis: Ability to distinguish between lvalues, rvalues, xvalues, and prvalues to predict compiler behavior.Move Constructor Implementation: Skill in writing Move Constructors that "steal" resources from temporary objects rather than performing expensive deep copies.Move Assignment Logic: Ability to implement safe Move Assignment operators that handle self-assignment correctly.Perfect Forwarding: Proficiency in using std::forward to pass arguments through template wrappers without losing their value category.Rule of Five Compliance: Capability to correctly implement (or delete) the Destructor, Copy/Move Constructors, and Copy/Move Assignment operators to manage resource handles.
STL & Algorithms
Container Selection Strategy: The ability to benchmark and select the correct container (e.g., std::vector vs. std::deque) based on access patterns and memory locality.Associative Data Handling: Competence in using std::map and std::set for sorted data storage and retrieval.Hash Map Optimization: Skill in using std::unordered_map and handling hash collisions for O(1) lookups.C++23 Container Usage: Familiarity with modern C++23 containers like std::flat_map for cache-friendly associative lookups.Iterator Traversal: Mastery of using iterators to traverse containers generically, decoupling data structure from algorithm logic.Lambda Expressions: Ability to write concise, inline anonymous functions with precise capture lists ([=], [&]) for custom logic.Algorithmic Efficiency: Proficiency in applying standard algorithms (std::sort, std::find, std::accumulate) rather than writing raw loops.Functional Programming in C++: Skill in using C++23 features like std::ranges::fold_left to write declarative, chainable data processing pipelines.
