设置Linux开发环境
- 启动WSL终端：在Windows搜索栏输入"Ubuntu"并打开
Ubuntu in Start Menu
- 首次启动会要求设置用户名和密码，请记住此密码，后续使用sudo命令时需要
- 更新系统包列表并安装GNU编译器工具和GDB调试器：
代码语言：bash
AI代码解释
sudo apt-get update sudo apt-get install build-essential gdb- 验证安装是否成功：
代码语言：bash
AI代码解释
whereis g++ whereis gdb如果安装成功，会显示g++和gdb的路径信息。
- 创建项目目录：
代码语言：bash
AI代码解释
mkdir projects cd projects mkdir helloworld cd helloworld在WSL中启动VS Code
在WSL终端中，进入项目目录并输入以下命令启动VS Code：
代码语言：bash
AI代码解释
code .首次启动时，VS Code会自动下载并安装WSL服务器组件。成功启动后，VS Code窗口标题栏会显示"WSL: Ubuntu"，状态栏会显示远程连接状态。
Remote context in the Status bar
安装C/C++扩展
- 在VS Code中打开扩展面板（Ctrl+Shift+X）
- 搜索"C/C++"扩展（由Microsoft提供）
- 如果已在本地安装，点击"Install in WSL"按钮将其安装到WSL环境中
Install in WSL button
安装完成后需要重新加载VS Code以生效。
创建和编写C++代码
- 在VS Code文件资源管理器中，点击"新建文件"按钮，创建
helloworld.cpp
New File title bar button
- 粘贴以下示例代码：
代码语言：cpp
AI代码解释
#include <iostream> #include <vector> #include <string> using namespace std; int main() { vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"}; for (const string& word : msg) { cout << word << " "; } cout << endl; }- 保存文件（Ctrl+S）
探索IntelliSense功能
VS Code的C/C++扩展提供了强大的IntelliSense功能：
- 悬停在
vector或string上查看类型信息 - 输入
msg.时会自动显示成员函数列表 - 自动补全功能可通过Tab键触发
Statement completion IntelliSense
运行C++程序
- 确保
helloworld.cpp是当前活动文件 - 点击编辑器右上角的"播放"按钮
- 在弹出的编译器选择中，选择"g++ build and debug active file"
C++ debug configuration dropdown
VS Code会自动生成tasks.json文件，用于配置构建任务。成功运行后，在集成终端中会看到输出：
代码语言：txt
AI代码解释
Hello C++ World from VS Code and the C++ extension!理解tasks.json
自动生成的tasks.json位于.vscode目录下，内容如下：
代码语言：json
AI代码解释
{ "version": "2.0.0", "tasks": [ { "type": "shell", "label": "C/C++: g++ build active file", "command": "/usr/bin/g++", "args": ["-g", "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}"], "options": { "cwd": "/usr/bin" }, "problemMatcher": ["$gcc"], "group": { "kind": "build", "isDefault": true }, "detail": "Task generated by Debugger." } ] }关键参数说明：
command: 指定编译器路径（g++）args: 编译参数，-g表示生成调试信息${file}: 当前活动文件${fileDirname}/${fileBasenameNoExtension}: 输出可执行文件路径和名称
