## Overview

This is a small C utility library with a demonstration program. The runtime workflow is: run the demo, exercise the string helpers, open the sample file, count its lines/words/characters, search it for matching lines, and print results. Build, library-packaging, installation, and documentation capabilities are described in the README but are not runtime components. The file utilities share one source file; their separate responsibilities are documented and visible in the sampled code.

Main entry points: [`src/main.c`](https://github.com/mohid525/bsdsf24m042-os-a01/blob/main/src/main.c) (Demo entry point), [`src/mystrfunctions.c`](https://github.com/mohid525/bsdsf24m042-os-a01/blob/main/src/mystrfunctions.c) (String helpers), [`src/myfilefunctions.c`](https://github.com/mohid525/bsdsf24m042-os-a01/blob/main/src/myfilefunctions.c) (File counting), [`test.txt`](https://github.com/mohid525/bsdsf24m042-os-a01/blob/main/test.txt) (Sample input)
