Hello C++ Codespaces Starter

A minimal C++ "Hello World" project configured for GitHub Codespaces, VS Code, and CMake.

Quick start (Codespaces)

1. Create a new repo on GitHub and add these files.
2. In the repo page, click Code > Codespaces > Create codespace on main.
3. After it opens, build and run:
   • Run task: Build (CMake) or press Ctrl/Cmd+Shift+B
   • Run the program:
     • Task: Run Hello
     • Or use Debug: "Run Hello (gdb)"

Quick start (local with VS Code)

• Install: VS Code, C/C++ extension, CMake Tools, and optionally Dev Containers.
• If using Dev Containers, open the repo folder in VS Code and "Reopen in Container" to match Codespaces.
• Build/Run via the provided tasks or CMake Tools commands.

Commands

• Configure: cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug
• Build: cmake --build build -j
• Run: ./build/hello

CI

A basic GitHub Actions workflow builds and runs the program on Linux.
