Unable to use remove() on string?

[burger87]

I have been trying to use remove() on a file name that is stored in a string variable with no success.

Is there any other way to do so?

I guess I wasn't clear enough(pun intended). Let me elaborate.

I want to delete a file. The file name consists of 3 parts, namely:
1) A value from an ini file.
2) A date.
3) The extension ".txt".
Eg. Name090422.txt

How do I delete this file?

You could call a system command which I wouldn't recommend.

OR

int remove(const char * filename);

remove("C:/deleteme.txt"); //should work. Notice the slash is different.
//I've heard of remove( "C:\\Deleteme.txt" ); format as well.

std::string filename = "...";
int result = remove(filename.c_str());

Remove takes a C string (char*), not a C++ string.

std::string filename = "...";
int result = remove(filename.c_str());

Thank you! I'm a newbie at C++ and this is exactly what I wanted.
Thanks again.
