【Trae】如何使用Trae编译C++（附带MinGW）
结果
先看结果
这是一道回文串题目，F5编译，控制台输入输出。
下载
- 下载Trae编译器，直接去官网下：https://www.trae.cn/
- 下载VSCode编译器，这个相信用Trae的各位都不陌生。https://code.visualstudio.com/
- 查看你的C盘，
C:\Users\Administrator\.vscode\extensions路径下是否有extensions.json文件，如果没有，请将VSCode卸载后重装。
- 查看你的C盘，
安装插件
在VSCode里安装“C/C++”插件。
这里需要在VSCode里安装的原因是C/C++插件在Trae里是搜不到的。
再次查看C:\Users\Administrator\.vscode\extensions路径，看看插件是否安装成功，且extensions.json文件里有这个插件。
关闭VSCode，打开Trae。
点击右上角头像-IDE设置
选择“从VSCode导入”，等待它导入插件，导入完成后点击查看一下，是不是下载的那些插件。
编译
新建一个文件夹，用Trae打开，再在里面新建一个cpp文件，输入一段HelloWorld代码。
会看到自动生成了一个.vscode文件夹。
在这里按F5运行，如果运行成功，会出现如下所示。
如果运行失败，请进行如下配置。
下载MinGW并安装到D盘（傻瓜式教学，跟着安就行，除非你知道要修改的json里每个参数的意义）
这里我贴心地给大家建了项目。
https://gitcode.com/qq_36286039111111111111111mq8/MyMinGW.git
把这个项目拉下来，MinGW放到D盘，bin文件夹的路径如下所示。
并且在环境变量的PATH里配置这个bin文件夹（相信各位对PATH都很熟悉）
接下来来到Trae，找到那个.vscode文件夹
c_cpp_properties.json

注意像我这样配置需要在项目目录下新建一个名为exe的文件夹，用于存储编译过后的文件。
{"version":"2.0.0","command":"g++","args":["-g","${file}","-o","${workspaceFolder}/exe/${fileBasenameNoExtension}.exe"],"problemMatcher":{"owner":"cpp","fileLocation":["relative","\\"],"pattern":{"regexp":"^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$","file":1,"line":2,"column":3,"severity":4,"message":5}},"tasks":[{"type":"cppbuild","label":"g++","command":"D:/MinGW/bin/g++.exe","args":["-fdiagnostics-color=always","-g","${file}","-o","${workspaceFolder}/exe/${fileBasenameNoExtension}.exe",""],"options":{"cwd":"D:/MinGW/bin"},"problemMatcher":["$gcc"],"group":{"kind":"build","isDefault":true},"detail":"调试器生成的任务。"}]}至此再去尝试编译，一般没什么大问题 ，报什么错就去解决一下就好了。
QA
- 如果控制台能编译成功就是不能输入数据怎么办？
我遇到了之后是MinGW版本问题，把原本的MinGW删了，装我在文章里给的那个。 - 报错找不到g++？
PATH没配置。
