Hi Happy New Year
I think U R not allocating the memory to the
pointer "buf" but using buf to get some data.
This is an error as buf may be pointing to some
illegal segments of data.
#include "malloc.h"
#define MAXDATA 2096
and add this line before the line gets(buf ....
buf = malloc(MAXDATA);
Hope this solves your error.
(Do allocate memory for word also)
