如何使用指针按字母顺序对双指针数组中的字符串进行排序

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

void sortStrings(char** arr, int n) {
    char* temp;
    int i, j;
    
    for (i = 0; i < n-1; i++) {
        for (j = 0; j < n-i-1; j++) {
            if (strcmp(arr[j], arr[j+1]) > 0) {
                temp = arr[j];
                arr[j] = arr[j+1];
                arr[j+1] = temp;
            }
        }
    }
}

int main() {
    char* arr[] = {"apple", "banana", "cat", "dog", "elephant"};
    int n = sizeof(arr) / sizeof(arr[0]);
    int i;
    
    printf("Before sorting:\n");
    for (i = 0; i < n; i++) {
        printf("%s ", arr[i]);
    }
    printf("\n");
    
    sortStrings(arr, n);
    
    printf("After sorting:\n");
    for (i = 0; i < n; i++) {
        printf("%s ", arr[i]);
    }
    printf("\n");
    
    return 0;
}

Before sorting:
apple banana cat dog elephant 
After sorting:
apple banana cat dog elephant
