需要帮助：C ++删除已知文件 [英] Need Help: C++ Delete Known File
问题描述
问候，
随着学校的学习开始。
处理程序并需要从已知位置删除文件<硬盘驱动器上的
，但无法完成任何工作。
我试图使用< cstdio>
但无法让它正常工作。我的参考书有以下
....
int remove（const char * fname）;
我在互联网上使用上面的相同信息找到了信息
以及if语句。当它返回-1时，它打印出Not
deleted"如果打印删除，则返回0。
但是，它永远不会删除文件。
我试图使用system（del c：\ deleteme.txt）;命令为
。当我调整上面的命令时，它继续说
文件不存在，即使它显示的路径是
文件的确切位置。
我讨厌要求代码，事实上我认为常见问题解答中有一些东西说b
说不要求它....但是有人可以直接在这里找我。 br />
或者我无法弄清楚如何正确使用remove（）或
某些东西是afu。 :)
谢谢你。
Greetings,
Onwards with the school studying.
Working on a program and need to delete a file from a known location
on the hard drive but cannot get anything I do to work.
I have tried to use the remove function that is included with <cstdio>
but cannot get it to work properly. My reference book has the
following....
int remove(const char *fname);
and I have found information on the internet using the same above
along with an if statement. When it returns -1 it prints out "Not
deleted" and when it returns 0 if prints "deleted".
However, it never deletes the file.
I have tried to use the system("del c:\deleteme.txt"); command as
well. When I have tweaked the above command, it continues to say the
file doesnt exist even though the path it shows is EXACTLY where the
file is.
I hate asking for code, in fact I think there is something in the FAQ
saying not to ask for it.... but can someone set me straight here.
Either I cannot figure out how to use the remove() properly or
something is afu. :)
Thanks gents.

尝试c：\\ deleteme.txt，或者更好的是，保存的表格/ me /
很多调试时间，如果我意识到它是等价的，c：/deteteme.txt。
[注意：通常，我没有注意到这种错误，直到我单身-stepping
我的程序直到系统/ fopen / ifstream /无论什么电话，并且在命令字符串的调试器转储中查找

Marshall Cline的C ++ FAQ中包含了这个问题。请参阅主题
''[15.16]为什么我不能在不同的目录中打开文件，例如
" .. \ test.dat"？ "在发布之前查看常见问题解答总是好的。
您可以在以下网址获取常见问题解答：

通常的答案在C ++中与在C中相同，并且在Steve Summit的C FAQ的Q.17.17中涵盖了
。

This issue is covered in Marshall Cline''s C++ FAQ. See the topic
''[15.16] Why can''t I open a file in a different directory such as
"..\test.dat"?" It is always good to check the FAQ before posting.
You can get the FAQ at:
http://www.parashift.com/c++-faq-lite/
The usual answer to that is the same in C++ as it is in C, and is
covered in Q. 19.17 of Steve Summit''s C FAQ. It is always good to
check the FAQ before posting. You can get the FAQ at:

我读过它们。
问题不在于使用\或/。无论我使用什么，我都无法删除
文件。
示例：
＃包括< cstdio>
int main（）
{
if（remove（" SEEBELOW"）== - ） 1）
perror（删除文件时出错）;
else
puts（文件已删除）;
返回0;
}
SEEBELOW是我尝试了很多不同的文件名和路径
用的东西。 c：/deleteme.txt ../deleteme.txt等
我甚至在c：\到
的每个目录中都创建了这个txt文件.exe所在的目录（在项目文件夹中调试）。
此代码也在网上，但仍无效。我很无能为力。
I have read them.
The issue is not in using a \ or a /. I cannot get it to delete the
file, regardless of what I use.
Example:
#include <cstdio>
int main()
{
if (remove("SEEBELOW") == -1)
perror ("Error deleting file");
else
puts ("File deleted");
return 0;
}
SEEBELOW is the file name and path that I have tried many different
things with. c:/deleteme.txt ../deleteme.txt ect
I have even created that txt file in every directory from c:\ to the
directory where the .exe is at (debug in projects folder).
This code is also right off the net and still doesnt work. I am
clueless on it.
