【Windows版】VScode配置C++开发环境

​

一、参考资料

Visual Studio Code 配置C/C++编译及调试环境
Windows下VSCode配置C++环境
VSCode配置C++官方文档
Get Started with C++ on Linux in Visual Studio Code

二、步骤

1. 下载安装VSCode

VSCode下载

2. 安装c++插件

点击左侧栏第五个，在搜索框内输入【c++】，安装c++插件。
​

3. 生成 c_cpp_properties.json 文件

Ctrl+Shift+P调出命令面板
	==》输入C/C++，选择【Edit Configurations(UI)】进入配置
	==》在.vscode文件夹中自动生成 c_cpp_properties.json 文件

修改配置：

• 编译器路径：D:/360Downloads/Software/MinGW/mingw64/bin/bin/g++.exe；
• IntelliSense 模式：gcc-x64；

4. 新建demo.cpp工程文件

#include<iostream>
using namespace std;
 
int main()
{
    cout << "hello world!" <<endl;
    return 0;
}

5. 生成 task.json 文件

task.json 文件，代码进行编译的配置文件。

选择 【Terminal】
	==》【configure task】
		==》【C/C++:g++.exe生成活动文件】

6. 编译cpp文件

shift+ctrl+B 执行编译，生成 demo.exe 文件。

7. 运行 demo.exe 可执行文件

按 ctrl+F5，运行 demo.exe。

8. 生成 launch.json 文件

launch.json文件，代码进行调试（debug）的配置文件。

选择 【Run】
	==》【Add Configuration
		==》【C++(GDB/LLDB)】
			==》【g++.exe - 生成和调试活动文件】

9. 调试 demo.exe

按 F5，调试 demo.exe。
或者
Run ==》Start Debugging

三、注意事项

• 生成 task.json 和 launch.json 文件之前，务必切换到 demo.cpp 或者 demo.c文件，否则自动生成的 task.json 和 launch.json 无法编译对应的 demo.cpp 和 demo.c。
• 建议不同的编程语言采用不同的文件夹。
• 将 .vscode 文件夹备份一份，以后需要的时候直接复制即可，不用再花时间进行配置了。
