stupid C question

$DEITY it's been forever since I mucked with C...

if I have:
char offset_filename[MAX};
<blah>
strcat(offset_filename,argv[1]);
strcat(offset_filename,".offset");

and I call the program like:
a /some/path/to/file

then offset_filename becomes /some/path/to/file.offset

how in the $PURGATORY do I modify that code to replace /some/path/to with 
/my/hardcoded/path/to so that calling the program like:
a /some/path/to/file

ends up with offset_filename being:
/my/hardcoded/path/to/file.offset

(note that 'file' is still pulled from the argv[1])

thanks!
