如何在C：\中访问文件 [英] how to access a file in C:\
问题描述
我下载了一个免费的c编译器，我正试图访问windows中的文件
目录c：\ program program \ ...但是当我发错时出错运行代码。
可能我的声明char * NAME错了。有人可以提出建议吗？
非常感谢。

char * NAME_SMS =" c：\\Program Files \\ \\\Palm \\Tungst \\Backup \\SmsDB.PDB" ;;
file_sms = fopen（NAME_SMS，" r"）;
if（file_sms == NULL）{
fprintf（stdout，" Error opening file.\ n）;
}
fclose（file_sms）;
当我运行代码时，我得到错误打开文件。信息。如果我尝试使用
char * NAME_SMS =" c：\Program Files \ Palm \Tungst \ Backup \SmsDB.PDB" ;;我得到一个
编译器错误：词法：未知转义序列`\P''
I downloaded a free c-compiler and I''m trying to access a file in a windows
directory c:\program files\... but I get an error when I run the code.
Probably my declaration char* NAME is wrong. Anybody can give a suggestion?
Thanks very much.

}
fclose(file_sms);
When I run the code I get the "Error opening file." message. If I try with
char* NAME_SMS = "c:\Program Files\Palm\Tungst\Backup\SmsDB.PDB"; I get a
compiler error: lexical: unknown escape sequence `\P''

由于路径名中存在''''（SPACE），您的系统可能需要
来包装双引号的字符串。此外，它可能知道
''/''替代''\\''
char * NAME_SMS =" \\ \\ c：/ Program Files / Palm / Tungst / Backup / SmsDB.PDB \"" ;;

Because of the presence of '' '' (SPACE) in the path name, your system probably
requires to wrap the string by double quotes. Also, it probably knows that
''/'' is an alternative to ''\\''
char* NAME_SMS = "\"c:/Program Files/Palm/Tungst/Backup/SmsDB.PDB\"";

char * NAME_SMS =" c：\\Program Files \\Palm \\Tungst \\Backup \\ SmsDB.PDB英寸;
尝试char * NAME_SMS =" c：\Program Files \ Palm \Tungst \Backup \SmsDB.PDB" ;;
file_sms = fopen（NAME_SMS，" r"）;
if（file_sms == NULL）{

确保file_sms是文件*。
当我运行代码时，我得到错误打开文件。信息。如果我尝试
with char * NAME_SMS =" c：\Program Files \Palm \Tungst \ Backup \SmsDB.PDB" ;;我得到了一个

file_sms = fopen(NAME_SMS, "r");

Be sure that file_sms is a FILE * .
When I run the code I get the "Error opening file." message. If I try with char* NAME_SMS = "c:\Program Files\Palm\Tungst\Backup\SmsDB.PDB"; I get a

如果那个不起作用，叫什么名字你正在使用的编译器？
If that don''t work, what is the name of the compiler you are using?

否。这是完全错误的。
No. It''s fully wrong.

如果那不起作用，你的编译器是什么名字使用？

任何体面的C编译器都会拒绝编译这样的代码。

Any decent C compiler will refuse to compile such a code.
