42 C++ Modules (CPP00 → CPP09)

This repository contains my implementation of the 42 Network C++ Modules, a progressive introduction to modern C++ programming with a strong focus on Object-Oriented Programming (OOP), memory management, and advanced language features.

Throughout these modules, I built a deep understanding of C++ from fundamentals to advanced concepts such as polymorphism, inheritance, templates, STL, and algorithmic problem solving.

Overview

The C++ modules are designed to progressively teach the core principles of C++ and Object-Oriented Programming through practical exercises.

Each module introduces new concepts while reinforcing previous knowledge.

What I Learned

🔹 Core C++ Fundamentals (CPP00 - CPP01)

• Namespaces and scope management
• Classes and object-oriented design
• Constructors and destructors
• Member functions and encapsulation
• Memory allocation (stack vs heap)
• Pointers and references
• File streams and basic I/O

---

🔹 Object-Oriented Programming (CPP01 - CPP04)

• Deep understanding of OOP principles
• Encapsulation, abstraction, inheritance, polymorphism
• Operator overloading
• Canonical form (Rule of 3 / Rule of 5 concepts awareness)
• Class relationships (composition & aggregation)
• Abstract classes and interfaces

---

🔹 Advanced OOP & Memory Control (CPP04 - CPP06)

• Subtype polymorphism
• Virtual functions and runtime polymorphism
• Exception handling (try / catch / throw)
• Type casting (static, dynamic, reinterpret, const_cast)
• Memory safety and controlled object behavior

---

🔹 Templates & Generic Programming (CPP07)

• Function and class templates
• Generic programming concepts
• Code reuse through abstraction
• Compile-time polymorphism

---

🔹 STL & Algorithms (CPP08 - CPP09)

• Standard Template Library (STL)
• Containers (vector, map, stack, etc.)
• Iterators and algorithm usage
• Data structure manipulation
• Sorting and searching algorithms
• Algorithmic thinking and optimization

---

🔹 Algorithms (CPP09 Focus)

In the final module, I implemented and worked with:

• Efficient sorting algorithms (hybrid approaches)
• Container-based data manipulation
• Performance-aware algorithm design
• Input parsing and large dataset processing

Tech Stack

• Language: C++98 standard
• Paradigm: Object-Oriented Programming (OOP)
• STL (Standard Template Library)
• Unix-based compilation (Makefiles)
• Memory management without modern smart pointers (manual control)
