结构体指针指向结构体数组

结构体指针可以指向结构体数组，可以通过指针来访问和操作数组中的每个结构体成员。下面是一个示例代码：

#include <stdio.h>

struct Person {
    char name[20];
    int age;
};

int main() {
    struct Person people[3] = {
        {"Alice", 25},
        {"Bob", 30},
        {"Charlie", 35}
    };

    struct Person *ptr = people;  // 指向结构体数组的指针

    for (int i = 0; i < 3; i++) {
        printf("Person %d: Name = %s, Age = %d\n", i+1, ptr->name, ptr->age);
        ptr++;  // 指针后移
    }

    return 0;
}

输出结果为：

Person 1: Name = Alice, Age = 25
Person 2: Name = Bob, Age = 30
Person 3: Name = Charlie, Age = 35
