arrays - gdb : in array while debugging VS code

Question

我在调试过程中无法查看数组的内容。而不是我看到的字符。

我的代码:

#include <stdio.h>

int main()
{
    char str[100] = {0};
    fgets(str, 100, stdin);

    return 0;
}

我在 VARIABLES 窗口中看到的内容:

但是当我尝试调试 int 数组时一切正常。

例子:

#include <stdio.h>

int main()
{
    int str[100];
    for (int i = 0; i < 100; i++)
    {
        str[i] = i+1;
    }
    

    return 0;
}

我看到的:

任务.json:

            ],
            "preLaunchTask": "C/C++: gcc.exe build active file"
        }
    ]
}

如何查看数组中的字符？

Answer 1

因为 pretty-printer 没有正确显示 utf-8 字符。要显示 utf-8 字符，请编辑 launch.json 中的 setupCommands:

  "setupCommands": [
    {
      "description": "Enable pretty-printing for gdb",
      "text": "-enable-pretty-printing",
      "ignoreFailures": true
    },
    {
      "description": "Fix pretty-printing for gdb",
      "text": "set charset UTF-8"
    }
  ],
