Define a sort function as below void sort(struct Employee * baseŋ, int n, int (*compareFunc)(struct Employee ** struct Employee **)) { qsort((void **)base,n,sizeof(void *),(int (*)(const void *,const void *))compareFunc); } Q1) What does the line in the provided sort function do? Describe each of the 4 arguments being passed to qsort. What do we need that big strange cast for the fourth argument?
