C++ Projects: Digital Piano To create a digital piano using C++, a combination of audio playback and a GUI is needed. The GUI provides visual representation of the keys, while audio playback generates sound. For both functions, we will utilize the lightweight and popular SDL2 library. --- ## 1. Setting Up the Environment ### Installing SDL2 **On Linux:** ```bash sudo apt install libsdl2-dev libsdl2-mixer-dev ``` **On Windows/Mac:** Download SDL2 from the [SDL official website](https://www.libsdl.org/). Follow the provided instructions to set up the environment and configure your compiler to include SDL2 headers and libraries. --- ## 2. Planning the Program - The piano keys will be displayed graphically as white and black keys. - Each key will play a specific sound when pressed. - Each key is linked to a corresponding sound file. - Mouse input is used to detect which key is pressed. --- ## 3. Code Implementation ```cpp #include <SDL2/SDL.h> #include <iostream> #include <m...

C++ Projects: Basic+ and Simple Search Engine   Creating a basic search engine using C++ involves multiple components, including parsing text files, indexing content, and enabling users to search for keywords efficiently. This project will guide you through building a simple search engine step by step. ## Steps to Build a Simple Search Engine   ### 1. Identifying the Issue   Before diving into coding, we need to establish the core functionalities of our search engine:   - **Parsing text files** to extract words.   - **Indexing words** to map them to file names and positions.   - **Allowing users to search** for different words and retrieving relevant results.   - **Structuring the program** efficiently for readability and scalability.   ### 2. Data Structure for Indexing   To store words and their occurrences, we use an **unordered_map** (hash table) in C++.   ```cpp unordered_map<stri...

C++ Projects: Basic Traffic Management System A traffic management system simulates traffic flow, manages signals, and ensures smooth operations. Components: Signals : Control vehicle flow at intersections. Vehicles : Simulate traffic movement. Logic of Intersection : Manages signal timing and crossing safety. Simulation : Displays real-time traffic flow. Tools Used: Classes : For modeling signals and vehicles. Functions : For controlling traffic flow. System Design TrafficLight Class Manages signals with three states: RED, YELLOW, and GREEN . Code: #include <iostream> #include <string> enum LightState { RED, YELLOW, GREEN }; class TrafficLight { LightState state; int timer; public: TrafficLight() : state(RED), timer(10) {} void changeState() { if (state == RED) { state = GREEN; timer = 15; } else if (state == GREEN) { state = YELLOW; timer = 5; } else { ...

C++ Projects: Basic Operating System It's a complex project, creating a basic operating system using C++ because it requires a good knowledge of computer architecture, programming, and OS concepts. First of all, it's needed to understand basic OS concepts such as: 1. Bootloader: Loading the OS into memory. 2. Kernel: The main area of the OS that manages software and hardware. 3. Memory Management: Allocation and management of system memory. 4. File Management: Organization of data and its storage. 5. Threads and Processes: Managing multitasking. 6. Drivers: Enabling hardware communication. ### Environment and Tools You will need: - **Cross Compiler**: A compiler to interact with the OS structure (GCC-based). - **Emulator**: For testing the OS (QEMU/Bochs). - **Makefile**: For automating the build process. - **Tools**: `ld` and `objcopy` to link and generate binaries. ### Writing Code for Bootloader This program is loaded by UEFI/BIOS to initialize the system and load the kernel...

C++ Projects: Database Management System A database management system in C++ involves creating various functionalities to manage, store, update, retrieve, and delete data from a database. File handling is used to simplify different functions, while the C++ standard library aids in processing. Creating a Basic DBMS in C++ Definition of Data Structure Storage of records can be implemented using a class or a similar structure to represent database entries. File Handling To save data persistently, file I/O operations are utilized. CRUD Operations CRUD refers to: Create : Adding new records to the database. Read : Fetching records based on criteria. Update : Modifying existing data. Delete : Removing records. User Interface Providing an interface for interacting with the database management system.
