## Overview

strin is a small C++ learning project that implements a raw-buffer string class and C-string-like operations. Its main workflow is interactive: the demo reads two lines, exercises copy, comparison, mutation, search, and length operations, then prints results. Stream input temporarily writes each line to a file before loading it into a string. All runtime code is in main.cpp; the README documents capabilities beyond the sampled implementation, so the graph groups related operations rather than implying separate modules.

Main entry points: [`main.cpp`](https://github.com/syampullamar/custom-string-class-in-c-/blob/main/main.cpp) (Interactive demo)
