文章介绍了在VSCode中遇到C++程序可以运行但无法调试的常见问题，提供了解决方案。通过修改launch.json中的program字段和添加preLaunchTask，并创建相应的task.json，设置preLaunchTask与task.json中的标签一致，从而使得调试功能正常工作。配置文件包括launch.json、tasks.json和c_cpp_properties.json的修改内容。

vscode运行C++:可运行但无法调试解决方案

问题描述

vscode中下载了c/c++ complie run和Code Runner，可以自动生成c++运行所需的配置文件（.vscode\launch.json、.vscode\settings.json、.vscode\c_cpp_properties.json），但是无法调试，调试时报错如下：
在这里插入图片描述

解决方案

1.修改 launch.json中的"program": “${fileDirname}\${fileBasenameNoExtension}.exe”,
2.在launch.json中添加"preLaunchTask": “mytask”,
3.ctrl+shift+p,创建task.json，将label改为"mytask",与"preLaunchTask"的值一致。
备注：“mytask”可以随便起，只要两者一致即可。

我的配置文件
