fscanf(file_current, "%-5d%-5d%-5d%-5d%-5d%-5d%-5d%-5d\n", &current->name_num, &current->title_num, &current->iden_num, &current->pro_num, &current->abi_num,&current->race_num, &current->item_num, &current->soc_num); 这个为什么有警告

这个警告可能是由于使用了格式字符串中的`-`标志导致的。

在`fscanf`函数中，`%-5d`表示读取一个带有宽度为5的十进制整数，并且左对齐。然而，这不是`fscanf`函数中标准的格式指示符。

为了消除警告，你可以将格式字符串调整为符合标准的格式指示符。对于你的代码示例，你可以使用`%5d`来读取整数，并且在后面添加一个空格来忽略换行符。

修改后的代码示例如下：

fscanf(file_current, "%5d%5d%5d%5d%5d%5d%5d%5d ",
    &current->name_num, &current->title_num, &current->iden_num, &current->pro_num,
    &current->abi_num, &current->race_num, &current->item_num, &current->soc_num);

通过这样修改格式字符串，可以消除警告并正确读取整数值。

void loadUserFile(pUserList ___) { FILE* _ = fopen("users.txt", "r"); if (_) { User __ = { 0 }; ___->_1 = 0; while (1) { if (fscanf(_, "%s ", __._1) != 1) break; if (fscanf(_, "%s ", __._2) != 1) break; if (fscanf(_, "%s ", __._3) != 1) break; if (fscanf(_, "%s ", __._4) != 1) break; if (fscanf(_, "%d ", &__._5) != 1) break; addUserList(___, &__); } fclose(_); } }

这段代码是用来读取一个名为 "users.txt" 的文本文件，该文件中包含已注册用户的信息。具体来说，它首先打开文件，然后使用 fscanf() 函数逐行读取文件中的内容，将每个用户的信息存储到一个 User 结构体变量中，并将该变量添加到 pUserList 类型的链表中，最后关闭文件。其中，__._1、__._2、__._3、__._4、__._5 分别代表 User 结构体中的 5 个成员变量，分别是用户名、密码、邮箱、性别和年龄。addUserList() 函数是一个自定义函数，用于将用户信息添加到链表中。

mm1¼fscanf(in,’%5d %5d’, [2,1]);

As an AI language model, I can only speculate about the intention of the code as there is no context provided. However, I can explain what this code is doing.

The code `fscanf(in, '] ]', [2,1])` is likely reading from a file stream `in`. It is trying to match the format string `'] ]'` with the input from the stream. The `]` characters are used as literal characters to match with the input stream. The two numbers `[2,1]` are the addresses of two variables that will receive the values read from the input stream.

The `mm1¼` part of the code seems unrelated and incomplete. It is possible that it is a variable or a function that is used elsewhere in the code. Without more context, it is difficult to say for sure.
