42 C++ Modules

From procedural instincts to object-oriented mastery.

About

This repository contains my solutions to the 42 Network C++ Modules (00–09).

The modules progressively introduce core concepts of C++ (C++98) — from the basics (classes, namespaces, I/O) to more advanced topics like inheritance, polymorphism, exceptions, casts, templates, and STL fundamentals.

The goal is not only to complete the exercises, but to build a strong understanding of how C++ works and how to write clean, maintainable OOP code.

Modules overview

Module	Focus	Key topics
cpp00	Basics	namespaces, classes, member functions, iostream
cpp01	Memory & references	new/delete, references vs pointers, file streams
cpp02	Ad-hoc polymorphism	operator overloading, canonical form
cpp03	Inheritance	base/derived classes, constructor/destructor chain
cpp04	Polymorphism	virtual functions, abstract classes, interfaces
cpp05	Exceptions	try/catch, custom exceptions
cpp06	Casts	static_cast, dynamic_cast, conversions
cpp07	Templates	function & class templates
cpp08	STL intro	containers, iterators, basic algorithms
cpp09	Mixed advanced usage	combining concepts, algorithms practice

Each module typically contains:

• exercise folders (ex00, ex01, ...)
• a Makefile
• subject-compliant *.cpp / *.hpp files

---

Build & run

All exercises are designed for C++98.

# Example: compile an exercise
cd cppXX/exYY
make

# Run
./<program>

The executable name depends on the exercise/Makefile.

---

Notes / rules followed

• C++98 only (per 42 subject)
• no external libraries unless explicitly allowed
• Makefile required for each exercise
• focus on correctness, clean design, and avoiding leaks (where applicable)
