Using unordered_map with dyanmically-allocated user-defined class - c++

Question

So I've got a class, "Room", which has the following code:
class Room
{
public:
Room(string name, string desc): name(name), desc(desc) {}
void operator=(const Room room)
{
name = room.name;
desc = room.desc;
}
string getName(); //returns this.name
string getDesc(); //returns this.desc
private:
string name; //name of the room
string desc; //description of the room
};
I've got a global variable in my main.cpp of type unordered_map, like this:
unordered_map<string, *Room> rooms; //Room's name is the key
And I want to allocate Rooms on the fly in a function and add them to my map. I attempted to do it like this:
void builder()
{
Room* room = new Room("Name", "Desc");
rooms[room->getName()] = room;
}
...But I'm getting all kinds of compiler warnings. I figured it would be something to do with iterators or hashing, or I'm not using pointers correctly (which are probably all true), but mostly it seems unordered_map doesn't like being parametrized with Room or *Room. Am I missing something?

Answer 1

There are some syntax errors as *Room. I have some tips
#include <string>
#include <memory>
#include <unordered_map>
using namespace std;
class Room
{
public:
Room(string name, string desc)
: name(name) // This syntax is called initializer list
, desc(desc)
{
}
void operator = (const Room room)
{
name = room.name;
desc = room.desc;
}
string getName() { return name; }
string getDesc() { return desc; }
private:
string name; //name of the room
string desc; //description of the room
};
// Without using unique_ptr you have a memory leak
// because the is not explicitly called the delete operator on pointers
unordered_map<string, std::unique_ptr<Room> > rooms;
void builder()
{
Room* room = new Room("Name", "Desc");
rooms[room->getName()].reset (room);
}
