Question

In C++

Write a program that calculates the occupancy rate for a hotel. The program should start by asking the user how many floors the hotel has. A loop should then iterate once for each floor. In each iteration, the loop should ask the user for the number of rooms on the floor and how many of them are occupied. After all iterations, the program should display how many room the hotel has, how many of them are occupied, how many are unoccupied, and the percentage of rooms that are occupied. The percentage may be calculated by dividing the number of rooms occupied by the number of rooms.

NOTE: It is traditional that most hotels do not have a thirteenth floor. The loop in this program should skip the entire thirteenth iteration.

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 1

#include<iostream>
using namespace std;
int main(){
  
   int n,room,occ,total_occ=0,total_room=0;
   // taking number of floors as a input
   cout<< "Enter the number of floors (greater then one)" << endl;
   cin >> n;
   while(n==1){
       cout << "Please enter the number of floor greater than 1"<< endl;
       cin >>n;
   }
      
   for(int i=1;i<=n;i++){
       if (i==13)
           continue;
       else{
           // taking number of room as a input
          
           cout << "Enter the total number of rooms on the "<< i << " floor (greater than 10) "<< endl;
           cin >> room;
           while(room<10){// if user enter number of room less than 10
               cout << "Please enter the number of room greater than 10"<< endl;
               cin >>room;
           }
          
           // taking number of occupied rooms as input
           cout << "Enter the total number of occupied rooms on the "<< i << " floor (less than total number of rooms) "<< endl;
           cin >> occ;
           while(room<occ){// if user enter number of room less than 10
               cout << "Please enter the number of occupied room less than total number of rooms "<< endl;
               cin >>occ;
           }
           // calcuating total number of rooms
           total_room=total_room+room;
           // calcuating total occupied number of rooms
           total_occ=total_occ+occ;
       }
      
   }
       // display total number of rooms in the hotel
       cout << "Total number of rooms in the hotel " << total_room << endl;
       // display total number of unoccupued rooms in the hotel
       cout << "Total number of unoccupued rooms in the hotel " << total_room-total_occ << endl;
       // display total number of occupied rooms in the hotel
       cout << "Total number of occupied rooms in the hotel " << total_occ << endl;
       // display percentage of occupied room
       float var=(float(total_occ)/float(total_room));
      
       cout << "Percentage of occupied room " << var *100 << "%"<< endl;
