在使用vs代码调试文件时,如何将文件传递给我的程序

我想启动一个带有文件的a.exe(已编译的cpp程序)。在CMD上我会像a.exe < input.txt那样做。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"
        }
    }
]}

作为args,我已尝试按照this post"<", "input.txt"this post的建议使用"<input.txt"。两者都不起作用。按照建议here调试cmd似乎是一种非常糟糕的做法。当我拥有vs代码的强大调试工具时,为什么要在cmd上进行调试?

我在Windows机器上运行。

您缺少的是告诉gdb文件的实际位置。尝试提供输入文件时,您需要将文件的位置放在引号中,因此看起来像这样:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++ - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [
                "<", "${fileDirname}/words5.txt"
            ],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                    
                }
            ],
            "preLaunchTask": "C/C++: g++ build active file",
            "miDebuggerPath": "/usr/bin/gdb"
        }
    ]
}
