📘 C++ Deep Dive

A topic-by-topic C++ reference: working programs and study notes, from first cout to smart pointers.

✨ About

I made this repo while working through Abdul Bari's Learn C++ Programming – Beginner to Advance – Deep Dive in C++ on Udemy. The programs are my own practice code, written and modified while following the course, and the notes are my own study notes. Each module pairs example programs with notes, so you can read a concept and run the code side by side.

I use it to revise, and I'm sharing it in case it helps other beginners too.

🚀 Getting started

git clone https://github.com/supreetvardhamane/cpp-deep-dive.git
cd cpp-deep-dive

g++ -std=c++11 "01-CPP-Basics/01 - area of circle.cpp" -o example
./example

Requirements: any C++11-compatible compiler (GCC, Clang, or MSVC). Some programs in 18-IO-Streams read from the .txt files in the same folder, so run them from that directory.

🧭 How to use this repo

1. Learning C++? Follow the modules in order, reading the notes first and then running the code.
2. Revising? Use the Quick find table or jump straight to a module.
3. Experimenting? Change the examples and recompile. Breaking them on purpose is a great way to learn.
