在 Visual Studio Code 中调试(C++ 程序)时无法看到矢量或其他容器(例如地图)的内容

Sun*_*mar 4 c++ gdb visual-studio-debugging visual-studio-code

我编写了一个简单的C++(11)程序来测试 Windows 中 Visual Studio Code 中的调试器。我使用 MinGW 发行版作为编译器选项。我已经按照此处的文档进行了设置tasks.jsonlaunch.jsonhttps: //code.visualstudio.com/docs/cpp/config-mingw

这是示例cpp代码:

typedef std::vector<int> vi;    
int main(int argc, char const *argv[])
{
    fast();
    int tests = 1;
    cin >> tests;
    while(tests--)
    {
        int n = 5, k = 25;
        cin >> n >> k;
        vi permutation(n);
        for (int i = 0; i < n; i++)
        {
            cin >> permutation[i];
        }

        // vi permutation = {5,4,3,2,1};
        auto ans = solve(permutation, k);
       // other logic goes here

    }
    return 0;
}

我在调试器窗口中看到以下内容: 在此输入图像描述

根据文档,我应该看到类似这样的屏幕: 在此输入图像描述

我在这里设置有问题吗?为什么我看不到容器的内容?我发现我也看不到其他容器的值。

当我从您提到的站点安装 MINGW 时,我遇到了同样的问题。然后我从wiki中提到的SourceForge安装了 MINGW ,它开始正常工作。请尝试一次。
