Data Structures

Collection of classic and advanced data structure implementations written in C/C++. The code is inspired by the course "Mastering Data Structures and Algorithms using C and C++" by Abdul Bari and is organised so each concept lives in its own folder.

Features

• Examples for arrays, linked lists, trees, graphs, heaps and more
• Simple, portable C/C++ code with minimal dependencies
• Build every example at once with make
• Suitable as a reference for students and hobbyists

Build

Clone this repository and run make to compile all programs:

git clone https://github.com/najm09/DataStructure.git
cd DataStructure
make

Compiled binaries will be placed next to their source files with the .app extension.

Contributing

Pull requests or fixes are always appreciated!
