一、vscode 配置c++环境

1、安装c++插件

2、下载c++编译器g++
下载链接：
https://sourceforge.net/projects/mingw-w64/

3、加压编译器并加入环境变量

4、配置vscode c++编译器
先创建个cpp文件

#include <iostream>
using namespace std;
 
int main() 
{
    cout << "Hello, World!";
    system("pause") ;
    return 0;
}

然后把改 “externalConsole”: true，这样调试c++就能通过vscode控制台查看

Copy
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++.exe - 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "E:\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "g++.exe build active file"
        }
    ]
}

5、重启vscode，运行测试

二、vscode离线插件包vsix安装

参考：https://blog.51cto.com/u_15291229/5042433
对应插件包文件打开终端：

code --install-extension  插件包

三、vscode打开新标签 不覆盖

参考：https://blog.csdn.net/weixin_43744149/article/details/129615517

设置里把workbench.editor.enablePreview选项

前面勾勾去掉

四、文件对比

左键ctrl选择两个文件，右键选择compare即可
