Thread: Access Dynamic path/folder with ios:ofstream

For Making long description short see my case:

Code:

suppose,

path: "../defult123/test.txt"

my code: ofstream fout("../defult123/test.txt",ios::out);

Here in "defult123", "default" is static but "123" is dynamic .So Basically 

path should be written as: "../default***/test.txt"

So how can i access this dynamic path for writing in test.txt file.

Code:

so should be working ??
ofstream fout("../default*/test.txt") 

or,do  i have to list directory fist then check for folder named "default" in sub folder? if so then how do i do that?

please be a help....

You are out of luck. You can only do that in a system() or exec() command.

In any case, an ofstream is one object referring to one specific file, it cannot be an indeterminate number of different files.

So what should i do for this problem?

Build the string that represents the filename, using whatever string building tools you like (stringstreams, etc.). Then pass the .c_str() of that string to your ofstream constructor.

If you're saying "how do I know what the number is on the file that's out there", then you'll probably want to do something system specific.

FindFirstFile Function is what made my day.Thanks mates.
