C ++重构数组

Question

Hi I'm new at C++ and I want to create an array like this but in C++:

    rooms {

        1 { 'name' : 'Room1' },
        2 { 'name' : 'Room2' }

    }

Can someone help me with this? Tanks for your time

Define a struct or class to represent the room data and use a std::vector , std::map or std::unorderd_map to store the rooms:

#include <iostream>
#include <vector>
#include <map>

struct Room {
   std::string name;
   Room(std::string _name) : name(_name) {}
   Room() {}
};

int main() {
    std::vector<Room> rooms{{"Room1"}, {"Room2"}};
    std::cout << rooms[0].name << std::endl; // prints "Room1"

    std::map<int, Room> roomsMap{
        {1, Room{"Room1"}},
        {2, Room{"Room2"}}
    };
    std::cout << roomsMap[1].name << std::endl; // prints "Room1"
    return 0;
}
