VScode多文件编译/调试配置

之前都是在Visual Studio写C/C++，最近想换到VScode，折腾半天把launch.json和tasks.json配好了（虽然不懂为什么，但确实能用了），在此做个记录。

参考资料：1，2，3

环境：win10

launch.json如下

{"configurations": [{"name": "C/C++: g++.exe build and debug active file","type": "cppdbg","request": "launch","program": "${workspaceFolder}\\${fileBasenameNoExtension}.exe","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb","miDebuggerPath": "E:\\mingw64\\bin\\gdb.exe","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true},{"description": "Set Disassembly Flavor to Intel","text": "-gdb-set disassembly-flavor intel","ignoreFailures": true}],"preLaunchTask": "C/C++: g++.exe build active file"}],"version": "2.0.0"}

tasks.json如下

{"tasks": [{"type": "cppbuild","label": "C/C++: g++.exe build active file","command": "E:\\mingw64\\bin\\g++.exe","args": ["-fdiagnostics-color=always","-g","${workspaceFolder}/*.cpp","-o","${workspaceFolder}\\${fileBasenameNoExtension}.exe"],"options": {"cwd": "${fileDirname}"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true},"detail": "Task generated by Debugger."}],"version": "2.0.0"}
