🚀 Phase 3: The First Test
1. Create a new file named hello.cpp.
2. Paste the code I wrote in the video
3. Build & Run (In VS Code Terminal):
● Build: g++ main.cpp -o myprogram
● Run: ./myprogram (Mac/Linux) or myprogram.exe (Windows)
❓ Troubleshooting
● "g++ is not recognized" (Windows): You must add C:\msys64\ucrt64\bin
to your System Environment Variables (Path).
● Missing Headers: Restart VS Code after the compiler installation to refresh the path.
