Can someone please help me write the functions C code, I have to use qsort.

The program sortMe.c uses the qsort function to sort an array of structures struct element {int id_number; char last_name[10]; float salary;}; You are to write the functions int compare_id_ascending (const void *, const void *); int compare_id_descending (const void *, const void *); int compare_name_ascending (const void *, const void *); int compare_name_descending (const void *, const void *); int compare_money_ascending (const void *, const void *); int compare_money_descending (const void *, const void *)
