从函数返回结构指针(数组)并打印出数据

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

Person* createPersonArray(int size) {
    Person* arr = (Person*)malloc(size * sizeof(Person));
    
    // 初始化数据
    for (int i = 0; i < size; i++) {
        sprintf(arr[i].name, "Person%d", i+1);
        arr[i].age = 20 + i;
    }
    
    return arr;
}

int main() {
    int size = 5;
    Person* arr = createPersonArray(size);
    
    // 打印数据
    for (int i = 0; i < size; i++) {
        printf("Name: %s, Age: %d\n", arr[i].name, arr[i].age);
    }
    
    // 释放内存
    free(arr);
    
    return 0;
}
