如何在结构数组中搜索字符串？

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

// 定义结构体
struct Person {
    char name[20];
    int age;
};

// 在结构数组中搜索字符串
int searchPerson(struct Person arr[], int size, const char* target) {
    for (int i = 0; i < size; i++) {
        if (strcmp(arr[i].name, target) == 0) {
            return i;  // 找到匹配项，返回索引
        }
    }
    return -1;  // 没有找到匹配项
}

int main() {
    struct Person people[] = {
        {"Alice", 25},
        {"Bob", 30},
        {"Charlie", 35}
    };
    int size = sizeof(people) / sizeof(people[0]);

    const char* target = "Bob";
    int index = searchPerson(people, size, target);

    if (index != -1) {
        printf("找到了 %s，年龄为 %d\n", people[index].name, people[index].age);
    } else {
        printf("未找到 %s\n", target);
    }

    return 0;
}
