The first line using strtok is being misused.  NULL is only used as the
string pointer calling argument in a call to strtok where a previous call
has received a string address and this new call is expected to begin where
the previous call left off.  Try looking at the compiler's documentation on
a function before using it.

After that line the remainder of the program is invalid because an invalid
address was given to strtok, a program which uses the address it is given to
modify memory, so undefined behavior is all that can be expected of what
remains.
