Question

Objectives:

1. Use if, switch, and loop statements

2. Use input and output statements

3. Incorporate functions to divide the program into smaller segments

Instructions:

Your task is to write a program that simulates a parking meter within the parking deck. The program will start by reading in the time a car arrives in the parking deck. It will then ask you what time the car left the parking deck. You should then calculate the time that has passed between issuing the time ticket and the time the car left. Lastly, you will use this information to determine how much the person needs to pay upon leaving the deck. The rates are in the table below. Please read through all of the notes below!

You should write a single function for each of the following things:

Reading in the arrival times and departure times

Calculate the passage of time

Determine how much the player needs to pay

Print out the receipt for the user. Including their arrival and departure times, time in the deck and how much they owe.

Notes:

Time should be handled in the 24 hour format for simplicity. In addition, you should put the data on a file with the hours and the minutes as two separate variables separated by a space. Please have the hours ranging from 0 to 23, and minutes ranging from 0 to 59 with a blank in between hours and minutes. See the second table below for the data.

You may assume that the parking deck is open 24/7 for simplicity. You do not need to worry about times the deck closes and such for this project.

If the drive has a special parking pass, please enter the time of 99 for the hour and 99 for the minutes when entering the deck. This should be used as a code for the system to know that this person has a special parking pass.

If the drive has lost their ticket, please input 55 for the hour and 55 for the minutes when exiting the deck. This will prompt the system to handle the payments without a ticketing stub.

Please make sure that the output is attractive and informative. It should include, but is not limited to: the time the ticket was issued the time the ticket was entered back into the machine (time the drive exited the deck.) You should also include the amount of time that transpired while the driver was in the deck and the amount of money due to pay back. Please use proper formatting techniques for output (fixed and set precision, remember we are talking about money.)

Rate Table:

Time in Parking Deck	Rate in Dollars ($)
Less than or equal to 30 minutes	3.00
> 30 Minutes <= 1 Hour)	5.00
>1 Hour <= 2 Hours )	10.00
>2 Hours <= 3 Hours )	15.00
>3 Hours <= 4 Hours )	30.00
Each half hour over four hours <= 12 hours	30.00 + 5.00 per additional half hour
>12 Hours <= 24 Hours )	Error prints out, see notes above.
Lost ticket	110.00
Special Parking Pass	5.00

Running:

Please run the following sets of data from an INPUT FILE:

	Entrance Hour	Entrance Minute	Exit Hour	Exit Minute
Run 1	00	00	00	30
Run 2	05	45	07	00
Run 3	06	32	09	54
Run 4	09	15	12	15
Run 5	09	32	14	35
Run 6	08	00	10	30
Run 7	08	45	55	55
Run 8	99	99	99	99

Extra Credit:

What happens if you were to arrive at 5:00 PM and leave at 4:00 AM? Would you program still run this correctly? Make sure that you can account for this sort of issue.

Answer 1

C++ code for the given problem:

#include<iostream>

#include<iomanip>

#include<cmath>

#include <string>

#include <fstream>

using namespace std;

//function to find the total parkTime

int findTotTime(int, int, int, int);

//function to calculate the fare

int estimateFare(int);

//print the refare details in the recept

void farePrint(int, int, int, int, int, int);

//The main

int main() {

//the run file

string str="run.txt";

//open the run file

ifstream is(str);

int enterHr, enterMin, exitHr, exitMin, parkTime, charge;

//the while loop to process each entries

while(is>>enterHr>>enterMin>>exitHr>>exitMin)

{

//call the functions

parkTime = findTotTime(enterHr, enterMin, exitHr, exitMin);

charge = estimateFare(parkTime);

farePrint(enterHr, enterMin, exitHr, exitMin, parkTime, charge);

}

//for visual studio

return 30 + ceil(x)*5;

}

return -1; //error

//print the refare details in the recept
