42 C++ Modules

Solutions to the 42 CPP modules (00–09), a series that walks through modern C++ from basic class design up to STL containers and templates.

Modules

Module	Topic
cpp-module00	Namespaces, classes, member functions, stdio, basic I/O
cpp-module01	Memory allocation, references, pointers to members, switch
cpp-module02	Ad-hoc polymorphism, operator overloading, orthodox canonical class form
cpp-module03	Inheritance
cpp-module04	Subtype polymorphism, abstract classes, interfaces
cpp-module05	Repetition and exceptions
cpp-module06	C++ casts (static_cast, dynamic_cast, reinterpret_cast, const_cast)
cpp-module07	Templates
cpp-module08	Templated containers, iterators, algorithms
cpp-module09	STL containers in practice (Bitcoin Exchange, RPN, PmergeMe)

Build & run

Each module has its own subdirectories per exercise, each with its own Makefile:

cd cpp-module00/ex00
make
./<executable>

Code is compiled with -Wall -Wextra -Werror -std=c++98 per the 42 norm.

What you'll see across the modules

• Encapsulation, the rule of three, and orthodox canonical form
• Inheritance, virtual functions, abstract base classes
• Operator overloading, function pointers, functors
• Exception handling
• Templates (function + class), template specialization
• STL containers (vector, list, map, stack) and iterators
