deleteing a file

i know its a stupid question..but how do i delete a file?

WinAPI:
DeleteFile

Or (cross-platform):

Code:

---

#include <cstdio>
using namespace std;

//...

remove("myfile.txt");

---

string sFileName = "c:\\abc.txt";
system("del"+sFilename);

Sorry daok, but beside that your solution is neither portable nor native, it won't work
string file = "c:\\abc.txt";
string command = "del " + file;
system(command.c_str());

i decided to use doaks, becaus ei need delete all of the .ppm files

i think that was a best way i had for now...thanks for the help
