DeleteFile() not working

I was trying the DeleteFile() function, and I wrote the program below.

#include <iostream>
#include <fstream>
#include <windows.h>
using namespace std;
int main(){
    FILE * filetxt;
    // creat a file
    filetxt = fopen("C:\\Users\\Thomas\\Desktop\\filetxt.txt", "w");

    // delete the file 
    if (DeleteFile("\\\\.\\C:\\Users\\Thomas\\Desktop\\filetxt.txt") != 0){
        cout<<"success";
    }else{
        cout<<"fail";
    }
    cin;
}

But the program didn't work as it was supposed to. The file created wasn't deleted.

The output is: 

fail

You opened the file with fopen and you called DeleteFile before closing it with fclose.

As you can read from DeleteFile MSDN documentation:

The DeleteFile function fails if an application attempts to delete a file that has other handles open for normal I/O or as a memory-mapped file (FILE_SHARE_DELETE must have been specified when other handles were opened).

Note also that, on failure, you can call GetLastError after DeleteFile to get an error code with more information about the cause of the failure.
