用c语言编写一个函数,从num个字符串中找出最长的一个字符串,并通过形参指针max传回该串地址

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

void findLongestString(char **strings, int num, char **max) {
    *max = strings[0];
    for (int i = 1; i < num; i++) {
        if (strlen(strings[i]) > strlen(*max)) {
            *max = strings[i];
        }
    }
}

int main() {
    char *strings[] = {"apple", "banana", "pear", "watermelon", "orange"};
    int num = sizeof(strings) / sizeof(strings[0]);
    char *max;
    findLongestString(strings, num, &max);
    printf("The longest string is: %s\n", max);
    return 0;
}
