VSCode 配置 C 语言编程环境

一、下载 mingw64

二、配置环境变量

三、三个配置文件

四、格式化代码

1、安装插件

2、保存时自动格式化

3、左 { 不换行

上了两年大学，都还没花心思去搭建 C 语言编程环境，惭愧，惭愧。

一、下载 mingw64

mingw64 是著名的 C/C++ 编译器 GCC 的 Windows 版本。

下载地址：MinGW-w64 - for 32 and 64 bit Windows download | SourceForge.net

① 进入网页后选择 Files 选项卡

② 往下划，找到最新版本的 mingw64，下载如下版本

③ 解压压缩包得到 mingw64 文件夹

mingw64 应该是一款绿色软件，安装和卸载的方法：下载文件夹和删除文件夹。

二、配置环境变量

① 右击 “此电脑”，选择 “属性”（如果你没有 “此电脑” 图标，那就去资源管理器找）

② 高级系统设置 << 环境变量...（在右下角）<< Path（双击或选中后点击 “编辑” 打开）

③ 新建环境变量，填入你的 mingw64 文件夹下 bin 目录的路径（不要照着写！）

④ 打开 cmd，输入以下指令，测试环境变量是否生效

gcc -v

如下图所示，测试成功：

如果出现类似 “不认识 gcc” 的报错，那么可能是路径写错了或者需要重启一下电脑？

三、三个配置文件

在你放代码文件夹下创建一个名为 “.vscode” 的文件夹，并在其中创建三个文件：

c_cpp_properties.json
launch.json
tasks.json

c_cpp_properties.json

注意：把所有的 C:/Program Files/MinGW 换成你的 mingw64 所在目录的路径！
