使用qsort对字符串数组进行排序

void qsort(void *base, size_t nmemb, size_t size, int (*compar)(const void *, const void *));

int compar(const void *a, const void *b);

#include <stdio.h>
#include <stdlib.h>
#include #include <string.h>

int compare(const void *a, const void *b) {
    return strcmp(*(const char **)a, *(const char **)b);
}

int main() {
    char *arr[] = {"apple", "banana", "orange", "grape"};
    int size = sizeof(arr) / sizeof(arr[0]);

    qsort(arr, size, sizeof(arr[0]), compare);

    for (int i = 0; i < size; i++) {
        printf("%s\n", arr[i]);
    }

    return 0;
}
