Overview

A C-based Personal Finance Tracker that allows users to manage their financial transactions with features like authentication, transaction management, reporting, and statistical analysis.

Features

• User Authentication: Sign-in, registration, and user verification.
• Transaction Management: Add, view, edit, and delete transactions.
• Reporting: Generate financial reports.
• Statistical Analysis: Analyze financial trends with mean, variance, and standard deviation.
• Data Visualization: Visualize transactions using matrix representation.
• Cross-Platform Compatibility: Works on different operating systems.

File Breakdown

auth.c/h

Handles user authentication with functions for sign-in, registration, and user verification. Uses file I/O for storing user credentials in CSV format, implements basic string operations and input validation. Core functions: signIn(), registerUser(), authenticateUser().

colors.h

Contains ANSI escape code definitions for terminal color output. Implements defines for RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, and RESET colors. Used throughout the application for visual feedback.

main.c/h

Program entry point and core structure definitions. Defines User and Transaction structs, handles the main menu loop, and coordinates between authentication and transaction modules. Uses standard C libraries (stdio.h, stdlib.h, string.h, math.h).

transactions.c/h

Core transaction management functionality with functions for CRUD operations, sorting, searching, and analysis. Implements file I/O for transaction storage, statistical calculations, and data visualization through matrix representation. Key functions include addTransaction(), viewTransactions(), generateReport(), analyzeTrends().

utils.c/h

Utility functions for input handling, screen clearing, color printing, and menu display. Implements cross-platform compatibility for screen clearing and input buffer management.

Mathematical/DS/Algorithm Concepts Used

• Statistical Analysis: Mean, Variance, Standard Deviation
• Sorting: Bubble Sort (transactions by amount), Selection Sort (by date)
• Matrix Operations: 2D array for transaction visualization
• File I/O: Binary and text file operations
• Recursion: Total calculation
• Data Structures: Structs, Arrays
• Search Algorithms: Linear search for transactions

User Flow Diagram

Building the Project

To compile the project and create an executable, follow these steps:

1. Ensure you have a C compiler installed (e.g., gcc).
2. Open a terminal or command prompt.
3. Navigate to the directory containing your project files.
4. Run the following command to compile the source files into an executable:

gcc -o finance_tracker main.c auth.c transactions.c utils.c

This will generate an executable named finance_tracker.

Authentication Instructions

When entering your password during sign-in or registration, the input will be masked with asterisks (*) for security. To toggle the visibility of the password, press the 'Tab' key while typing your password.
