Deleting a File by Name

Hi,
I have a program where I need the user to input the filename to be deleted.
This is what I have so far:

#include <iostream.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>
#include <fstream.h>
#include <string>

using namespace std;
string delfilename;

int delfile()
{
system("CLS");

cout<<"Enter File to be Deleted"<<endl;
cin>>delfilename;
system("del delfilename.c_str()"); // delete file
system("PAUSE");
}

Thanks

I would recommend:

remove(delfilename.c_str()); // delete file

To use, #include <cstdio>

Works perfect!
Thanks
