## Overview

Quant Learning Lab is a self-paced quant-internship learning repository: learners study fundamentals, implement exercise stubs, check their work, and track progress. Its major branches include Python, C++, math, computer science, finance, portfolio projects, and interview preparation. The README documents the learning workflow and capabilities; sampled source confirms representative exercise modules and the C++ TODO/test helpers, but does not establish calls among the larger project and interview materials.

Main entry points: [`basics/cpp/common/todo.hpp`](https://github.com/kihyu/quant-learning-lab/blob/main/basics/cpp/common/todo.hpp) (TODO Marker), [`basics/cpp/01_basics/ex_basics.hpp`](https://github.com/kihyu/quant-learning-lab/blob/main/basics/cpp/01_basics/ex_basics.hpp) (C++ Basics), [`basics/cpp/02_stl/ex_stl.hpp`](https://github.com/kihyu/quant-learning-lab/blob/main/basics/cpp/02_stl/ex_stl.hpp) (C++ STL), [`basics/cpp/03_memory/ex_memory.hpp`](https://github.com/kihyu/quant-learning-lab/blob/main/basics/cpp/03_memory/ex_memory.hpp) (C++ Memory)
