COMS 4995 — C++ Deep Dive

Course work and experiments for COMS 4995 (C++ Deep Dive).

Goals

• Practice modern C++ (C++17/20) with an emphasis on correctness, performance, and readability
• Build intuition for language fundamentals (value categories, RAII, move semantics, templates)
• Get comfortable with tooling (compiler warnings, sanitizers, debugging, formatting)

Repository structure

This repo will grow over the semester. Typical folders you may see:

• notes/ — lecture notes and references
• labs/ — small guided exercises
• hw/ — homework assignments
• projects/ — larger projects / final project

Tooling

Recommended:

• Compiler: clang++ or g++
• Build system: cmake (when projects start using it)
• Formatter: clang-format
• Static analysis (optional): clang-tidy

Useful flags:

• Warnings: -Wall -Wextra -Wpedantic -Werror
• Debugging: -g
• Sanitizers (Clang/GCC): -fsanitize=address,undefined

Build & run (example)

When a CMake project exists under a subfolder (e.g. labs/lab01/):

cmake -S . -B build
cmake --build build
./build/<executable-name>

For single-file experiments:

clang++ -std=c++20 -O2 -Wall -Wextra -Wpedantic main.cpp -o main
./main

Conventions

• Keep code warning-clean at high warning levels
• Prefer small, focused commits with clear messages
• Add a short README.md in each lab/homework folder with build/run instructions

Notes

If you’re a classmate/instructor looking at this repo: some folders may be empty or private until their release dates.
