## Overview

This repository is a C/C++ learning course made up of standalone C examples, not a single application runtime. The documented learner journey moves from language fundamentals toward data structures, algorithms, and integrated practice; the tree currently contains examples through pointers. Chapter ordering and later roadmap topics are based on the README, while implementation details are limited to the sampled source.

Main entry points: [`01-char-string-and-ASCII/test.c`](https://github.com/charleslizz/cpp-dsa-learning/blob/master/01-char-string-and-ASCII/test.c) (Characters and ASCII), [`02-dataType/test.c`](https://github.com/charleslizz/cpp-dsa-learning/blob/master/02-dataType/test.c) (Data Types), [`03-constant-type-conversion/test.c`](https://github.com/charleslizz/cpp-dsa-learning/blob/master/03-constant-type-conversion/test.c) (Constants and Conversion), [`04-printf-scanf/test.c`](https://github.com/charleslizz/cpp-dsa-learning/blob/master/04-printf-scanf/test.c) (Formatted I/O)
