Advertising is evolving in strange ways. It took some time to recognize the language (looks like C, but the this suggest OO, so C++ was a candidate), but it runs when compiled as C++.

#include "stdio.h"
#include "string.h"

struct cool {
  char p1, p2, p[5];
  cool(int c) : p2(c++), p1(c) {
    strcpy(p, "v_ga");
    p[1]=p2; p2=p[3]; p[3]=c;
    printf("www.%s.com/feladvany", this);
  }
} leet('n');

int main (int argc, char const* argv[])
{

  return 0;
}
