是否可以在某处下载本地(非cygwin)版本的DDD？

当我尝试使用MinGW-builds在64位主机上编译32位程序时:

T:\mingw64>.\bin\g++ -m32 Test.cpp

我明白了:

我想启动 a.exe （一个已编译的 cpp 程序）并传递一个文件到其中。在 CMD 上我会这样做a.exe < input.txt。如何在调试模式下使用 VS Code 启动它？

这是我的 launch.json 文件：

{
"version": "0.2.0",
"configurations": [
    {
        "name": "C++ Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceRoot}/a.exe",
        "args": [
            "<",
            "input.txt"
        ],
        "stopAtEntry": false,
        "cwd": "${workspaceRoot}",
        "environment": [],
        "externalConsole": true,
        "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",
        "linux": {
            "MIMode": "gdb"
        },
        "osx": {
            "MIMode": "lldb"
        },
        "windows": {
            "MIMode": "gdb"
        }
    }
]}

正如args我已经尝试使用的"<", "input.txt"那样，就像这篇文章中的那样以及这篇文章"<input.txt"中的建议。两者都不起作用。按照此处的建议，在 cmd 上进行调试似乎是一种非常糟糕的做法。当我拥有很棒的 VS …

如何调试mingw构建的二进制文件以检测堆错误？我看到关于这个主题有几个问题,但它们很通用,很难找到适合MinGW的工具.我花了很多时间来寻找解决方案,我希望合并后的主题会有所帮助.

当有人在Visual Studio调试器下运行它时报告库中的错误时,这样的工具就变得必要了,它会因"堆错误"而停止.

    if (x>0 && x<6) 
    {
        break;
    }
    else if(x>6)
    {
        break;
    }

相对

    if (x>0) 
    {
        if (x<6) 
        {
            break;
        }
    }
    else
    {
        if (x>6) 
        {
            break;
        }
    }
        

代码 1 不起作用，但代码 2 起作用。为什么？我是编程方面的超级菜鸟，所以请提供任何帮助。编程语言是C。
