Add file into folder

For example, I want to write file "a.txt" into D:\program, and I did
FILE* f=fopen("D:\program\a.txt","wb").
I only want the path of file to be D:\program, but
FILE* f=fopen("D:\program","wb") is wrong.

Didn't understand your question, anyway if you are trying to create a diretory use function CreateDirectory , like CreateDirectory("C:\\test",NULL);

I want to create output directory and save "a.txt".
I'm not sure about <windows.h>
Can you help me?

Yes.

i think you are not familiar with windows programming. windows.h is one of the basic header we need.

this link contains some tutorials on windows programming. http://www.winprog.org/tutorial/start.html[^]

you can crate a directory by calling the function CreateDirectory.

later you can write the file to that directoryusing fopen(filename,"w") and using fwrite or fprintf or whatever.

You're not escaping the backslash correctly. If you want to open a file in C:\some_dir you have to use:

"C:\\some_dir\\a.txt"

as the directory name otherwise the compiler thinks there're escaped 's' and 'a' characters in the string.

Cheers,

Ash

PS: As you're using C++ don't mess about with fopen and the like. Use the stream classes unless you have to be backward compatible with C.

PPS: On Windows you can't open directories the way you can under old versions of UNIX.

For more details:
I am implementing command arguments
<File_Name> <Output_Directory>
EX:
<File_Name> : D:\a.txt
<Output_Directory> : D:\Compressed
but finally
Output: D:\Compressed\a.huf

Dear Adamjohnvt,

It is not the way to create a file in folder or write in a file. In this regard, Please read the following:

You well be wrong: Note that the OP is using C++: this could well be native code, in which case .NET classes and procedures do not apply. For native code, fopen is perfectly valid.

Difficult to be precise, but there are two things that pop to mind:
1) You are trying to create a file called "program" in the root of the D: disk which contains a folder called "program" allready.
2) You are trying to create a file called "program" in the root of the D: disk which contains no such file or folder.

If the first case:

Yes, that is wrong.
What do you expect to happen?
Look at it this way:
When you file a letter in a file cabinet, do you try to write all letters on the file divider? Or on individual sheets of paper that you insert into the file divider?

You must specify the file name when you use fopen or you are trying to write to the folder, which you are not allowed to do.

If the second case:

Do you have permission to write to the root directory of the D: drive?
