这有什么问题。 （文件） [英] What is wrong with this. (files)
问题描述
好。我很尴尬地问这个，但我似乎无法获得
文件。我不知道问题是什么。有什么东西
错了:(文件相关）
#include< stdio.h>
main（） {
FILE * pfsin;
pfsin = fopen（" msm.pfs"，" r"）;
char mystr [100 ];
fscanf（pfsin，"％s"，mystr）;
fclose（pfsin）;
}
谢谢你的高级，但是我看过几个看起来像这样的代码的例子
EXACLTY这样，出于某些原因我的编译器给了我
rediculus错误。

C89上面的两行代码无序。
还有其他问题，
但是让我们看看我们是否可以让你先编译。
fscanf（pfsin，"％s"，mystr）;
fclose（pfsin）;
}
感谢高级，
但是我看到了几个看起来像这样的EXACLTY的代码示例，并且出于某种原因我的编译器给了我
rediculus错误。

最有可能的错误不是rediculus。 （原文如此）。快速浏览
您的代码会显示以下内容：
（a）main（）的声明错误。
（ b）C89不允许将声明与其他声明混合。
（c）不检查fopen（）返回状态。
（d）使用幻数 100.
（e）调用fscanf（）时缓冲区溢出的风险。
（f）缺少返回语句。

是的，这有点不对劲。阅读深红色
彩色iculus错误信息可能会给你一个线索。我可以看到
至少三个明显的错误，以及至少两个更多的战术错误。

Okay. I''m quite embarased to be asking this but I cannot seem to get
files to work. I don''t know what the problem is. Is there something
wrong with this: (file related)
#include <stdio.h>
main() {
FILE *pfsin;
pfsin = fopen("msm.pfs", "r");
char mystr[100];
fscanf(pfsin, "%s", mystr);
fclose(pfsin);
}
Thanks in advanced, but I have seen several examples of code that looks
EXACLTY like this, and for some reason my compiler is giving me
rediculus errors.

The above two lines of code are out of order for C89.
There''s other problems too,
but let''s see if we can get you compiling first.
fscanf(pfsin, "%s", mystr);
fclose(pfsin);
}

Most likely the errors are not "rediculus" (sic). A quick glance at
your code brings up the following:
(a) Wrong declaration for main().
(b) C89 does not allow mixing declarations with other statements.
(c) No check for fopen() return status.
(d) Use of "magic number" 100.
(e) Risk of buffer overflow in call to fscanf().
(f) Missing return statement.

Yes, there is something wrong with that. Reading the crimson
colored iculus error messages may give you a clue. I can see at
least three glaring errors, and at least two more tactical errors.
