Ok, every time I run my little application it leaves behind a text file called C:\debug.txt.

I would like my app to delete this.  

What command/code do I need to use in VC++ to delete this file?  

Thank you!

One approach:
http://www.cplusplus.com/reference/clibrary/cstdio/remove/
/* remove example: remove myfile.txt */
#include <stdio.h>

int main ()
{
  if( remove( "myfile.txt" ) != 0 )
    perror( "Error deleting file" );
  else
    puts( "File successfully deleted" );
  return 0;
}

Open in new window

For full path, you may need \\ as in:
remove("c:\\debug.txt");

Open in new window

Oh, I forgot to mention that you should close your file before deleting it.

You didn't mention how you open and close, but in case you need this, here is sample code from:
     http://www.cplusplus.com/reference/iostream/ofstream/close/
     // ofstream::open
#include <fstream>
using namespace std;

int main () {

  ofstream outfile;

  outfile.open ("test.txt", ofstream::out | ofstream::app);
  outfile << "This sentence is appended to the file content\n";
  outfile.close();

  return 0;
}

Open in new window
