Question

Write a program that calculates the occupancy rate for each floor of a hotel. (Use a sentinel value and please point out the sentinel in bold.) The program should start by asking for the number of floors in the hotel. A loop should then iterate once for each floor. During each iteration, the loop should ask the user for the number of rooms on the floor and the number of them that are occupied. After all the iterations, the program should display the number of rooms the hotel has, the number of them that are occupied, the number that are vacant, and the occupancy rate for the hotel. Input Validation: Do not accept a value less than 1 for the number of floors. Do not accept a number less than 10 for the number of rooms on a floor.

Answer-

Your code and output is given below as your requirement -

• #include <iostream>
• using namespace std;
• int main()
•    {  
• cout<<"\t**********Information of Hotal that show some statistics **********\n";
•   
• const int numberof_FLOORS = 1;
• const int numberof_ROOMS = 10;
• int floors;
• int rooms; //variable define
• int occupied;   
• int totalRooms=0, totalOccupied=0;
•   
• cout<<" Enter the number of floors,\n";
• do{
• cout<<"(Do not accept a number less than "<<numberof_FLOORS
• <<")\n";
• cout<<"Number of floors: ";
• cin >>floors;
• }while(floors<numberof_FLOORS); // input validation
•   
• cout<<"****************************************************\n";
•   
•   
• for(int floor=1; floor <= floors; floor++){
•   
• if(floor == 13){ //// Loop over all the floors to get the data.
• continue;
• }
•   
•   
• cout<<"Enter the number of rooms in floor \""
• <<floor<<",\"\n"; //// Get the number of rooms in each floor,
• do{
• cout<<"(Do not accept a number less than "<<numberof_ROOMS
• <<")\n";
• cout<<"Number of rooms: ";
• cin >>rooms;
• }while(rooms<numberof_ROOMS);
•   
• totalRooms += rooms;
•   
• cout<<"*************************************************\n";
•      
• cout<<"Enter the number of occupied rooms,\n";
• do{
• cout<<"(Do not accept a number less than 0)\n";
• cout<<"(it also could not be more than "<<rooms<<"\n";
• cout<<"Number of occupied rooms: ";
• cin >>occupied;
• }while(occupied<0 || occupied>rooms);
•   
• totalOccupied += occupied;
•   
• cout<<"**************************************************\n";
• }
•   
• // ---------------------------------------------------------
• // Display Information of Hotal that show some statistics
• cout<<"Display Information of Hotal that show some statistics\n";
• cout<<" Total number of rooms: "<<totalRooms<<std::endl;
• cout<<" Total number of occupied: "<<totalOccupied
• <<std::endl;
• cout<<"Total number of free ones: "
• <<(totalRooms-totalOccupied)<<std::endl;
• cout<<" Percentage of occupied: "
• <<1.0*totalOccupied/totalRooms<<std::endl;
•   
• cout<<"********************************************************\n";
• return 0;
• }
•
