I don't know how you got this to compile.  There are several errors.

crispin is an array of char but zunliang is an array of pointers to
char, as is fauzi.

cris is an int while liew and ogy are pointers to int.

this is ok.

> strcpy(fauzi, zunliang);

these are not. in this context while crispin is pointer to char,
zunliang is a pointer to a pointer to char.  type mis-match and
requuires a compiler diagnostic.
