Bulls and Cows (Console OS Pet Project)

Console implementation of the classic "Bulls and Cows" game in C++ with a client–server architecture and operating system mechanisms (shared memory, inter‑process communication). The project was originally created as a course work in operating systems.

Main Features

• Console "Bulls and Cows" game.
• Separation into two applications: client and server.
• Shared types and utilities extracted into include/ (SharedMemory, SharedTypes, etc.).
• CMake-based build system.
• Repository structure suitable for further development and experimentation.

Tech Stack

• Language: C++
• Build system: CMake
• OS concepts: shared memory, inter‑process communication, synchronization
• Environment: console applications

Project Structure

• client/ – client application (Client, client main.cpp).
• server/ – server application (Server, Game, server main.cpp).
• include/ – shared headers and implementations (SharedMemory, SharedTypes, etc.).
• CMakeLists.txt – root CMake configuration.

Build

From the project root directory:

mkdir build
cd build
cmake ..
cmake --build .

After a successful build, separate client and server executables will be generated (exact paths depend on your CMake configuration).

Run

1. Build the project (see above).
2. Start the server in one console.
3. Start the client in another console and connect to the server.
4. Play "Bulls and Cows" through the console interface.

What I Learned

• Practical experience with OS concepts: shared memory and inter‑process communication.
• Designing a small but complete client–server system in C++.
• Organizing a C++ project with modular structure and CMake build system.
