File statistics program written using some low level operating systems methodologies in C.

File Statistics with Interprocess Communication in C

This program calculates various statistics for text files, including newline count, word count, character count, and maximum line length.

Usage

To use the program, follow these steps:

1. Compile the program using a C compiler:

   gcc PosixMessageQueue.c -o file_stats

2. Run the program with the following command-line flags:

   ./file_stats [OPTIONS] [FILES]

   Replace [OPTIONS] with one or more of the following flags to specify the statistics to calculate:

   • -l: Calculate newline count.
   • -w: Calculate word count.
   • -c: Calculate character count.
   • -L: Calculate maximum line length.

3. The program will display the requested statistics for each file.

Example

To calculate the newline count and word count for a file named "input.txt", run the following command:

./file_stats -l -w input.txt

The program will output the newline count and word count for the specified file.

Notes

• The program supports processing multiple files simultaneously. Simply provide the file names as separate arguments.
• If no file names are provided, the program will use a default file.
• The program uses message queues for inter-process communication between the parent and child processes.
• The program relies on the POSIX message queue API and may require a POSIX-compliant operating system.
