如何使用C++中的数据结构函数？

#include <array>
#include <iOStream>

int main() {
    std::array<int, 5> arr = {1, 2, 3, 4, 5};

    std::cout << "Array size: " << arr.size() << std::endl;

    for (int i = 0; i < arr.size(); i++) {
        std::cout << "Element at index " << i << ": " << arr[i] << std::endl;
    }

    arr[2] = 10;

    std::cout << "Modified element at index 2: " << arr[2] << std::endl;

    return 0;
}

#include <list>
#include <iostream>

int main() {
    std::list<int> linkedList;

    // 添加元素到链表的末尾
    linkedList.push_back(1);
    linkedList.push_back(2);
    linkedList.push_back(3);

    // 添加元素到链表的前面
    linkedList.push_front(0);

    // 删除链表末尾的元素
    linkedList.pop_back();

    // 删除链表前面的元素
    linkedList.pop_front();

    // 遍历链表并打印元素
    for (int element : linkedList) {
        std::cout << "Element: " << element << std::endl;
    }

    return 0;
}
