noob programmer needs a hand with file IO =(

Been working on this for a whole day now. I need to write text at a particular point in a file.

CODE:

Code:

/* fseek example */

#include <stdio.h>



int main ()

{

FILE * pFile;

pFile = fopen ( "myfile.txt" , "w" );

fputs ( "This is an apple." , pFile );

fseek ( pFile , 9 , SEEK_SET );

fputs ( " sam" , pFile );

fclose ( pFile );

return 0;

}

OUTPUT:

This is an apple. sam

SHOULD BE:

This is a sample.

Could it be my compiler? I just have a crappy one that I downloaded online somewhere.

fflush(pFile)

after my first fputs() doesn't work either. =(

If you are opening the file using "w" that means its created newly and so it does not have a position you are specifying because fseek cannot put a pointer beyond EOF.
