None CULTY OF ENGINEERING AND INFORMATION TECHNOLOGYJEPARTMENT OF Computer ScienceQ3) Assume each Building has an id, number of rooms and consist of array of rooms. Each object ofclass Room has a length and width attributes and Arca() method. The following code represents theabove description.Note that the pointer in class building points to array of rooms.class Roomint length, width;public:int area () :class Building {int id ;const int num;//number of roomsRoom r;public:building (int, int , Room );int sum ();Hint: In all your answers, implement all the methods out of the classes1. Define a constructor with parameters for class Building to initialize its data members. Hint:create all the rooms inside the constructor2. Implement the sum method in the class building. (it returns sum of area of the rooms in thebuilding).3. Write setter and getter in class room.2 Rocm * a : this-snium (nun)

r is an array of Room objects and thus we can set the values of length and width of each room in…
