using namespace std;
class ClassRooms
{
public:
ClassRooms(int nRooms=100)
: numRooms(0), rooms(new ClassRooms[nRooms]) { }
~ClassRooms()
{
delete [] rooms;
}
void addRoom(const ClassRooms& cr)
{
rooms[numRooms++] = cr;
}
string findRoom(int seats)const;
int getSeats();
double getAreaPerSeat();
string getRoomNumber();
private:

double length, width;

Answer 1

You have no Classrooms constructor that takes a (string, int, double, double), so therefore, this ClassRooms(roomNum, seats, len, wid) is an error. You can easily add an appropriate constructor to Classrooms though.
ClassRooms(string roomNum, int seats, double len, double wid){
//do something
}
