Text File Analyzer

A small but powerful command-line tool written in C that analyzes text files and reports useful statistics—such as:

• Total characters
• Total words
• Total lines
• Character frequency
• Word frequency

It’s designed to be simple, fast, and easy to extend. The project uses a custom hash table for efficient word counting and a modular analyzer engine.
