Newbie problem, fopen

[o.fithcheallaigh]

Hello,

I am hoping someone can help with a problem I am having. I need to open a file to write an int and a float to it. So, I have been trying to build up my understanding to do this, so I figured I would try and get a small prohram working first. But that plan isn't going so well.

The program is

/* fopen example */
#include <stdio.h>
int main ()
{
  FILE * pFile;
  pFile = fopen ("myfile.txt","w");
  if (pFile!=NULL)
  {
    fputs ("fopen example",pFile);
    fclose (pFile);
  }
  return 0;
}

Now, can I ask, do I need to create an empty file called myfile? Or shoukd the program do that? If I do need to make the file, how does the program know where to find it??

I have been reading the documentation, but I don't really find answers to these questions, they all assume a specific amount of understand to begin with it seems.

Any help or advice would be fantastic! I want to learn how to do this, I don't want anyone to do it for me, but I do need to have some things explained.

Also, is there an error in this program??

I hope that's cool.

Thanks in advance.
