charCounter is a lightweight C utility designed for basic text analysis. It reads a text file character-by-character and provides statistics on characters and words, including unique word detection and word frequencies.
- ✅ Character counting
- ✅ Word tokenization based on space and newline
- ✅ Hash table-based word frequency tracking
- ✅ Unique word listing
- ✅ Console and file output support
- ✅ Lightweight and modular code
The program uses fgetc() to read characters from a file and builds words dynamically. These words are inserted into a hash table for tracking frequency. Once the file is parsed, it prints:
- Each character (if enabled)
- Words as they are formed
- A list of all unique words (words occurring only once)
The program is controlled using flags:
-c– Enables character counting-w– Enables word parsing and frequency tracking
You can configure the behavior based on which flags are set in the code.
