#include #include #include /* qsort int comparison function */ int int_cmp(const void *a, const void *b) { const int *ia = (const int *)a; // casting pointer types const int *ib = (const int *)b; return *ia - *ib; /* integer comparison: returns negative if b > a and positive if a > b */ } /* integer array printing function */ void print_int_array(const int *array, size_t len) { size_t i; for(i=0; iprice); /* float comparison: returns negative if b > a and positive if a > b. We multiplied result by 100.0 to preserve decimal fraction */ } /* qsort struct comparision function (product C-string field) */ int struct_cmp_by_product(const void *a, const void *b) { struct st_ex *ia = (struct st_ex *)a; struct st_ex *ib = (struct st_ex *)b; return strcmp(ia->product, ib->product); /* strcmp functions works exactly as expected from comparison function */ } /* Example struct array printing function */ void print_struct_array(struct st_ex *array, size_t len) { size_t i; for(i=0; i Execution result: *** Integer sorting... 7 | 3 | 4 | 1 | -1 | 23 | 12 | 43 | 2 | -4 | 5 | -4 | -1 | 1 | 2 | 3 | 4 | 5 | 7 | 12 | 23 | 43 | *** String sorting...
