2. Encapsulation
3. Inheritance
4. Polymorphism
5. Modern C++ Overview
6. Best Practices

1.1 Scope

This guide provides a comprehensive explanation of Object-Oriented programming in modern C++ (C++17/20). The content has been completely updated to reflect contemporary best practices including:

• Smart pointers and modern memory management
• Move semantics and rvalue references
• Const-correctness and RAII principles
• Modern constructor patterns and initializer lists
• Standard Library containers and algorithms
• Type safety and compiler-assisted correctness

The guide emphasizes pedagogical clarity over so-called "real world examples". Still, it shows current best practices and code patterns.

2. Release notes (2.0.0)

Major Update: Complete modernization to C++17/20 standards with comprehensive improvements.

What's New in This Version:

• ✅ All code examples updated to modern C++ (C++17/20)
• ✅ Smart pointers throughout (no more raw new/delete)
• ✅ Move semantics and rvalue references explained
• ✅ Const-correctness and RAII principles emphasized
• ✅ Fully compilable example code in examples/ directory
• ✅ CMakeLists.txt for easy building
• ✅ Modern C++ Overview guide for quick reference
• ✅ Best Practices document with industry patterns
• ✅ Compilation scripts for all examples

Previous Release (1.0.0):

This was the first edition of this guide. It used outdated C++ patterns that no longer reflect modern best practices.

Topics Covered:

• ✅ Object-Oriented fundamentals (classes, objects, abstraction)
• ✅ Encapsulation and access control
• ✅ Inheritance and class hierarchies
• ✅ Polymorphism and virtual functions
• ✅ Move semantics and modern memory management
