format ‘%s’ expects argument of type ‘char *’, but argument 3 has type
‘char **’ [-Wformat]:
> fscanf(finp, "%s", &alst[i]);
And in this case, you need to allocate char *arls[100] before using it.

As I already told you, this is a basic programming error but you event
didn't notice it. So please find good C books and references out there
and start learn how to write C program.
