如何設置 VSCode C++ 以顯示局部變量

Question

我正在關注 Udacity 的 C++ 納米學位課程。 在本課程中，講師使用 VSCode、C/C++ 擴展和 Clang 格式。

根據課程說明，我已經安裝了 g++ 編譯器和 gdb 調試器，這兩個工具都工作正常。 我遇到的問題是，當我嘗試從 VSC 調試時，我得到的結果與 tue 講師所顯示的完全不同。 我正在使用以下代碼

#include <iostream>
#include <string>
#include <vector>

using namespace std;

int main() {
  std::vector<std::string> brothers{"David", "Ethan", "Adam"};
  for (std::string const &brother : brothers) {
    std::cout << "Hello " << brother << "!\n";
  }
}

我的調試顯示了一些奇怪的信息。

這與講師在他的屏幕上看到的不同（他在 Linux 上）。 他正在獲取局部變量的實際內容。

這是launch.json 我用於調試器

        "type": "cppdbg",
        "request": "launch",
        "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",

                "ignoreFailures": true
            }
        ],
        "preLaunchTask": "C/C++: g++.exe build active file"
    }
]

}

我是一名中級 python 程序員，剛從 C++ 開始； 我的猜測是我的 VSCode 顯示的是一些 memory 分配或類型變量的東西，但這對於軟件調試不是很有用。 有人知道如何配置 VSCode 或編譯器以正確顯示變量的內容嗎？ 我正在使用 Windows。

謝謝！

我卸載了 minGW，從這個站點http://mingw-w64.org/doku.php/download安裝了 MinGW-w64，更改了 MinGW 環境變量，問題解決了！

謝謝！
