Book Review Tracker

A terminal-based application for managing personal book reviews with persistent storage. Built in C as a learning project to explore file I/O, memory management, modular programming, and user input validation.

Features

Core Functionality

• Add book reviews with title, author, written review, and star rating (1-5)
• Display all submitted reviews in professionally formatted output
• Identify and highlight highest-rated books with visual ratings
• Automatic file persistence to bookreview.txt
• Review summary statistics including average ratings

Technical Implementation

• Comprehensive error handling and input validation
• Dynamic memory allocation with proper cleanup
• Modular function-based architecture with separate utility files
• Robust file I/O operations with formatted output
• Enhanced user interface with progress indicators and visual separators

Version History

v2.2 - Current

• NEW: Enhanced visual formatting with consistent separators and headers
• NEW: Professional output styling with progress indicators
• NEW: Visual star rating system (filled/empty stars)
• NEW: Review summary statistics and analytics
• NEW: Improved user interface with section organization
• Better error messaging and user feedback

v2.1

• NEW: Modular code structure with separate utility files

v2.0

• Added persistent file storage
• Implemented comprehensive error handling
• Improved modular code structure
• Enhanced input validation and user feedback

Utility Functions

The project includes reusable utility functions for input handling:

• clear_input_buffer() - Clears leftover input after scanf operations
• trim_newline() - Removes trailing newlines from fgets input
• print_header() - Creates consistent formatted section headers
• print_mini_separator() - Adds visual separation between sections

These utilities can be reused in other C projects for robust input handling and professional output formatting.

Future Enhancements

• Edit and delete functionality for existing reviews
• Search capabilities by title or author
• Export options (CSV, JSON)
• Reading list and wishlist features
• Enhanced rating system with multiple categories
• Color-coded terminal output
• Review sorting and filtering options

Learning Outcomes

This project provided hands-on experience with:

• Memory management and leak prevention
• File I/O and data persistence patterns
• Error handling strategies in C
• Modular programming and code organization
• Header file creation and management
• User interface design for command-line applications
• Professional output formatting and user experience design
• Software versioning and iterative development
