如何在普通数组的单元格中插入结构或指针？c++

#include <iostream>

struct MyStruct {
    int value;
    std::string name;
};

int main() {
    const int size = 5;
    MyStruct arr[size];

    // 插入数据
    arr[0] = {10, "Alice"};
    arr[1] = {20, "Bob"};

    // 访问数据
    std::cout << "Value: " << arr[0].value << ", Name: " << arr[0].name << std::endl;

    return 0;
}

#include <iostream>
#include <string>

struct MyStruct {
    int value;
    std::string name;
};

int main() {
    const int size = 5;
    MyStruct* arr[size];

    // 创建结构体实例并插入指针
    MyStruct s1 = {10, "Alice"};
    MyStruct s2 = {20, "Bob"};
    arr[0] = &s1;
    arr[1] = &s2;

    // 访问数据
    std::cout << "Value: " << arr[0]->value << ", Name: " << arr[0]->name << std::endl;

    return 0;
}

#include <iostream>
#include <string>

struct MyStruct {
    int value;
    std::string name;
};

int main() {
    const int size = 5;
    MyStruct** arr = new MyStruct*[size];

    // 动态创建结构体实例并插入指针
    arr[0] = new MyStruct{10, "Alice"};
    arr[1] = new MyStruct{20, "Bob"};

    // 访问数据
    std::cout << "Value: " << arr[0]->value << ", Name: " << arr[0]->name << std::endl;

    // 释放内存
    for (int i = 0; i < size; ++i) {
        delete arr[i];
    }
    delete[] arr;

    return 0;
}
