我是C ++的新手，我正在学习矢量和所有有趣的东西。我试图找出如何让用户在他选择的楼层添加房间。我已经完成了大部分问题，但只是那部分我很难搞清楚，任何帮助都将不胜感激！我认为主要问题是在ReplaceFloor函数中，但我不知道如何以用户选择Choice 4的方式进行，然后进入他想要添加房间的楼层，并让楼层矢量存储一个更多的空间。提前谢谢你的帮助！我尽力让它尽可能地理解 - 抱歉，我很新。

答案 0 :(得分：0)
据我了解，您希望修复replaceFloor功能，以便您可以为特定楼层再添加一个房间。
在代码中，您可以使用以下行正确识别建筑物矢量中楼面元素的位置：if (newBuilding[i].getFloorID() == floorForRoomAdd)
除了您已完成的步骤之外，您还需要将房间实际添加到地板矢量中。为此，您可以访问楼层向量newBuilding[i]，然后调用newBuilding[i].push_back(newRoomObject)，其中newRoomObject包含您为要添加的新楼层指定的所有信息。这将导致房间被添加到地板矢量中。
如果我以任何方式误解了您的查询，请提及，以便我可以更新我的答案。我有一个查询但由于缺乏声誉而无法发表评论，为什么你在插入室功能中使用了newFloor.insert(newFloor.begin()+3, newRoom);。我可以看到+3常数的唯一原因是你可能会认为你说前两个位置是由floorID和房间号占用的。即使在那种情况下，也应该是+2。此外，即便如此，floorID和room no很可能是两个整数（或一些数字），而房间是对象。您不能在数组中混合使用这些类型。请澄清。
