CPP Modules

A series of C++ exercises covering object-oriented programming fundamentals through advanced topics. Each module builds on the previous one, progressing from basic syntax to STL containers and algorithms. All code follows the C++98 standard.

Building

Every exercise includes a Makefile. To build and run an exercise:

cd cpp00/ex00
make
./megaphone "hello world"

Common Makefile targets:

Target	Description
make	Build the exercise
make clean	Remove object files
make fclean	Remove object files and executable
make re	Rebuild from scratch
