# Vscode執行C++

1. **安裝[Vscode](https://code.visualstudio.com/)**
2. **安裝[MinGW](https://sourceforge.net/projects/mingw/files/)** (按`Download Latest Version`，檔名是mingw-get-setup.exe，MinGW其實就是C++編譯器)，然後install `mingw32-gcc-g++`和`mingw32-base`
3. **將MinGW的安裝路徑`C:\MinGW\bin`加入系統環境變數**

4. **安裝Vscode的C/C++套件**
5. **建置json檔案**

先在專案資料夾中建立`.vscode`的資料夾，然後在其中建立以下幾個json檔

// c_cpp_properties.json，程式碼自動完成 (IntelliSense)
