c_cpp_properties.json配置代码如下：
{ "configurations": [ { "name": "Win32", "includePath": [ "${workspaceFolder}", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed", "C:/MinGW_W64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include" ], "defines": [ "_DEBUG", "UNICODE", "_UNICODE" ], "compilerPath": "C:/MinGW_W64/mingw64/bin/gcc.exe", "cStandard": "c11", "cppStandard": "c++17", "intelliSenseMode": "clang-x64" } ], "version": 4}
问题一：
Failed to parse "\.vscode\c_cpp_properties.json": ENOENT: no such file or directory, open '\.vscode\c_cpp_properties.json'
地址肯定没错，变量名没变
问题二：
"compilerPath":“<path>"
当中path是gcc.exe还是clang.exe。网上还看到过C:/LLVM/bin/gcc.exe 。。。。
问题三：
setting.json是不是可有可无。

问题一我不知道
问题二，你想用哪个就填哪个
问题三，那叫settings.json，不叫setting.json。是可以没有，但如果有，别打错字了，否则就跟没有一样。
