My Harvardx CS50P Projects and Notes

HDF5-IO in Julia for the LEGEND experiment

Introduction to programming with C.

Project where I used Java to create a user verification system that reads user information from a CSV file where the credentials are stored, allows users to enter their login credentials, and provides feedback on their login status.

A Java program for analyzing stop-and-frisk data from the NYPD. Features data import, organization, and statistical analysis to compare occurrences during and after policy implementation.

A comprehensive Java program for analyzing and managing events and data points within a fictional spiderverse. Features event handling, anomaly detection, cluster management, and robust file I/O operations.

A Java program for performing detailed forensic analysis on data files. Features data extraction, comprehensive analysis, and report generation. Utilizes OOP principles, file I/O operations, and advanced analysis algorithms.

A Java program for reading student data from a file, calculating average test grades, determining letter grades, and computing overall average grades. Utilizes OOP principles, file I/O operations, and grade calculation algorithms.

Java-based application for managing and processing climate and economic information for USA communities using a layered linked list structure. Features include CSV data import, efficient data management, and retrieval methods. Ideal for learning and applying OOP and linked lists.

Java-based restaurant management simulation involving menu, stock, transactions, and guest seating. Utilizes hash tables, linked lists, queues, and OOP principles. Features include menu and stock management, order processing, donations, and transaction recording.

CERN ROOT compatiblility for Julia

Java implementation of Conway's Game of Life showcasing skills in OOP, GUI development, and algorithmic logic. Features an interactive, customizable grid, real-time controls, generation tracking, and pattern loading. Utilizes arrays for grid management and custom libraries for rendering and file I/O operations.

"Line-by-Line File Reader"

Practice tasks for complete Python programming language, including OOP and DSA concepts.

Comparing the efficiencies of linear, binary, and ternary searching algorithms in Python, Java, C++, and JavaScript

This repository contains a simple community management system implemented in C++. It allows users to add, display, update, remove, sort, and search for community members. The project utilizes a linked list to manage members efficiently and includes functionality for storing member details in a text file.

File I/O module for the PAZ Engine. Code for reading and writing data in various formats, including the PAZ Archive creation utility. No external dependencies. Like all PAZ Engine modules, this library can be used without the rest of the engine.

Tiny IO utility library for Rust to serialize/deserialize Serde compatible structs

GhostLogger is a hidden Windows keylogger that records keystrokes in Record.txt. For educational purposes !
