Changing a Second Value withing a Vector Object in C++ - c++

Question

I'm quite new at C++, and am learning about vectors and all that fun stuff. I'm trying to figure out how I can have the user add a room on his selected floor. I have most of the problem done, but just that part I am having a hard time figuring out, any help would be appreciated! The main issue I think is at the function ReplaceFloor, but I have no idea how to make it in a way that the user selects Choice 4, then enters the floor that he wants a room to be added, and have that floor vector store one more room in it. Thank you for your help in advance! I tried to make it as best understandable as I could- sorry I'm quite new.

As far as I understand, you want to fix the replaceFloor function so that you can add one more room to a particular floor.
In the code, you correctly identify the position of the floor element inside the building vector using the line: if (newBuilding[i].getFloorID() == floorForRoomAdd)
In addition to the steps you have done, you also need to actually add the room to the floor vector. For that, you can access the floor vector as newBuilding[i] and then call newBuilding[i].push_back(newRoomObject) where newRoomObject contains all the information you have specified for the new floor to be added. This will result in the room to be added in the floor vector.
If I have misunderstood your query in any manner, please mention that so I may update my answer. One query which I have, but can't comment due to lack of reputation is, why have you used newFloor.insert(newFloor.begin()+3, newRoom); in the insert room function. The only reason for the +3 constant I can see is that you may be thinking that you are saying that the first two spots are taken up by floorID and room no. Even in that case, it should be +2. Also, even then, floorID and room no will most probably be two integers (or some number), whereas the rooms are objects. You cannot mix those types in an array. Please clarify.
