Question

I am unable to create a directory using the following program :

#include <direct.h>
#include <iostream>
using namespace std;
int main() {
if(_mkdir("d:\ff") == 0) {
    cout << "success";
} else {
    cout << "fail";
  }
}

This program outputs fail .why is it so ?

The compiler that i am using is microsoft visual c++ 2010 express

You need to escape your back slash.
