Question

A computerised bus charges fare from each of its passengers based on the distance travelled as per the tariff given below:

Distance (in km)	Charges
First 5 km	₹ 80
Next 10 km	₹ 10/km
More than 15 km	₹ 8/km

As the passenger enters the bus, the computer prompts Enter distance you intend to travel. On entering the distance, it prints his ticket and the control goes back for the next passenger. At the end of journey, the computer prints the following:

1. the number of passenger travelled
2. total fare received

Write a program to perform the above task.
[Hint: Perform the task based on user controlled loop]

Answer 1

import java.util.*;
public class Q11
{public static void main(String args[])
{ Scanner in = new Scanner(System.in);
int cnt = 0;
double dist = 0.0, chrg = 0.0, tot = 0.0;
System.out.println("At any time, type 0 to quit");
while (true)
{System.out.print("Enter the distance you intend to travel: ");
dist = in.nextInt();
if (dist == 0)
break;
else
{if (dist <= 5.0) 
chrg = 80.0;
else if (dist <= 15.0)
chrg = 80.0 + 10 % (dist - 5.0);
else if (dist > 15.0)
chrg = 80.0 + (10.0 * 10.0) + (dist - 15.0) * 8.0; 
System.out.println("Ticket Cost: Rs. " + chrg);
tot = tot + chrg;
cnt++; 
} // lend of else block
} 
System.out.printin("\n\nThe number of passengers travelled: " + cnt);
System.out.printIn("The total fare received: " + tot);
}}
