C++ Modules 00–09

A collection of C++ projects completed as part of the 42 curriculum.

The modules introduce object-oriented programming and gradually progress toward templates, STL containers, algorithms, and advanced data-processing problems.

Modules

Module	Main Topics
CPP00	Namespaces, classes, member functions, initialization lists
CPP01	Memory allocation, pointers, references, file streams
CPP02	Orthodox Canonical Form, operator overloading, fixed-point numbers
CPP03	Inheritance and class hierarchies
CPP04	Polymorphism, abstract classes, interfaces, deep copying
CPP05	Exceptions, forms, and bureaucratic workflows
CPP06	C++ type casting and serialization
CPP07	Function and class templates
CPP08	STL containers, iterators, and algorithms
CPP09	Bitcoin Exchange, Reverse Polish Notation, and merge-insertion sort (Ford-Johnson Algorithm)

Each module contains multiple exercises with its own source files and Makefile.

Compilation

Navigate to an exercise directory:

cd CPP00/ex00
make

Run the generated executable:

./program_name

The executable name depends on the exercise.

Makefile Commands

Command	Description
make	Compile the exercise
make clean	Remove object files
make fclean	Remove object files and executable
make re	Recompile the exercise
