Word Count Utility

This project is my own reimplementation of the Unix command-line utility wc. It provides word count statistics for a given file. The program supports counting bytes, lines, words, and characters. It can also handle multi-byte characters based on the locale of the computer.

Features

• Count bytes (-c)
• Count lines (-l)
• Count words (-w)
• Count characters (-m) depends on the locale

Usage

$ ./wc [OPTION] [FILE]

Options:

-c: Outputs the number of bytes.
-l: Outputs the number of lines.
-w: Outputs the number of words.
-m: Outputs the number of characters (handles multi-byte characters based on the locale).

Example:

This command will display counts for all metrics.

$ ./wc sample.txt
42      67      1337    sample.txt

Handling Input from Stdin:

The program can also handle input from stdin, allowing you to use it in combination with other commands. For example:

$ cat test.txt | ./wc [OPTION]

This command will read the content of test.txt via cat and provide word count statistics.

Handling Manual Input:

You can also manually input text when running the program without a file. Simply run:

$ ./wc

After running the command, you can type or paste the text manually, and the program will provide word count statistics once you press Ctrl + D (Unix/Linux) or Ctrl + Z (Windows) to signal the end of input.

Build and Run

To build the program, you can use a standard C compiler:

$ gcc wc.c helper.c -o wc

To run the program:

$ ./wc [OPTION] [FILE]
