Question

Summary

The cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows.

If the number of rooms booked is:

• at least 10, the discount is 10%
• at least 20, the discount is 20%
• at least 30, the discount is 30%

Also if rooms are booked for at least three days, then there is an additional 5% discount.

Instructions

Write a program that prompts the user to enter:

1. The cost of renting one room
2. The number of rooms booked
3. The number of days the rooms are booked
4. The sales tax (as a percent).

The program outputs:

1. The cost of renting one room
2. The discount on each room as a percent
3. The number of rooms booked
4. The number of days the rooms are booked
5. The total cost of the rooms
6. The sales tax
7. The total billing amount.

Your program must use appropriate named constants to store special values such as various discounts.

Since your program handles currency, make sure to use a data type that can store decimals with a precision to 2 decimals.

SOLUTION:-

#include<iostream>

using namespace std;

int main()

{

double rent, s_tax, discount = 0;

int n, days;

double roomRent, totalRent,sales_tax;

// Entry of user

cout<<"Enter the rent of one room:$ ";

cin>>rent;

cout<<"Enter the number of rooms to be booked: ";

cin>>n;

cout<<"Enter the number of days for which rooms need to be booked: ";

cin>>days;

cout<<"Enter the sales tax (in %): ";

cin>>s_tax;

// if rooms is greater than or equal to 30,give the discount of 30%

if(n>=30)

discount = 0.3;

// if rooms is greater than or equal to 20,give the discount of 20%

else if(n>=20)

discount = 0.2;

// if rooms is greater than or equal to 10,give the discount of 10%

else if(n>=10)

discount = 0.1;

// if days is greater than or equal to 3 add additional 5%

if(days>=3)

discount += 0.05;

// calculation of total rent

totalRent = rent*n*days*(1-discount);

roomRent = totalRent/n;

// print the output

cout<<"The cost of renting one room is "<<roomRent<<endl;

cout<<"The discount given is "<<100*discount<< "%.\n";

cout<<"The number of rooms booked is "<<n<<endl;

cout<<"The number of days rooms booked is "<<days<<endl;

cout<<"Total cost of the rooms = "<<totalRent<<endl;

sales_tax = (s_tax*totalRent)/100;

cout<<"Sales tax = "<<sales_tax<<endl;

// generate total bill

cout<<"Total bill = "<<totalRent + sales_tax<<endl;

return 0;
