Given the following Seat class: class Seat private: string person name; bool isReserved; public: Seat () { person name="N/A"; isReserved=false; } bool reserveFor (string name); bool isFree (); void makeFree (); string whoIsSitting (); } ; Each seat can be occupied by only one person; we can reserve a seat for a person using the resereveFor member function. If the seat is occupied, the isFree function returns false. We make a seat free by calling the makeFree function. The function whols Sitting returns the name of the person sitting on the seat; if it is empty, it returns "N/A". Assume that the Seat class is implemented fully and ready to use, 1. Write a new class called Room. The room class should have 30 seats (private data). Also, write the below four member functions in the Room class. 2. Write bool EnterPerson(string name) member function that can be used to enter a person to the room. You need to give him the first seat available and return false if the room is full. 3. Write bool isRoomFull() member function which returns true if the room is full and false otherwise. 4. Write int SearchPerson(string name) member function which searches for given name and return the seat number of the person if he was in the room otherwise return -1. Valid seat numbers are 0 to 29.

Transcribed Image Text:Given the following Seat class:
class Seat
{
private:
string person name;
bool isReserved;
public:
Seat () { person name="N/A"; isReserved=false; }
bool reserveFor (string name);
bool isFree ();
void makeFree ();
string whoIsSitting() ;
} ;
Each seat can be occupied by only one person; we can reserve a seat for a person using the resereveFor member function. If the seat is
occupied, the isFree function returns false. We make a seat free by calling the makeFree function. The function whols Sitting returns the name of
the person sitting on the seat; if it is empty, it returns "N/A".
Assume that the Seat class is implemented fully and ready to use,
1. Write a new class called Room. The room class should have 30 seats (private data). Also, write the below four member functions in the
Room class.
2. Write bool EnterPerson(string name) member function that can be used to enter a person to the room. You need to give him the first seat
available and return false if the room is full.
3. Write bool isRoomFull() member function which returns true if the room is full and false otherwise.
4. Write int SearchPerson(string name) member function which searches for given name and return the seat number of the person if he was in
the room otherwise return -1. Valid seat numbers are 0 to 29.
