Design Specifications
Write, compile and test a C program with appropriate user-defined functions (modular design)
and comments to calculate parking fee. The program must meet the following specifications:
a) Prompt the user to input the vehicle type. ‘c’ or ‘C’ for a car, ‘m’ or ‘M’ for a motorbike, ‘t’
or ‘T’ for a truck. Display a message 'Wrong vehicle typewhen the input character is
other than specified.
b) Prompt the user to input the parking time in hours. The parking time is supposed to be a
positive integer number greater that 0 and less or equal to 24. Therefore, one hour
minimum charge is applied. The program should validate the input time.
The program should display a message 'Wrong parking time when the entered time is not
positive,or Parking time is limited to 24 hrswhen the entered parking time is >24. If the
entered time is not an integer number (for example 5.3) it must be rounded up (to 6 in this
example).
c) Calculates the amount charged based upon the following rates:
car - $3.50 p/h, motorbike - $1.50 p/h, truck - $8.00 p/h
However, if parking time is longer than 3 hrs, a 20% discount rate is applied (after 3 hrs).
If parking time is longer than 10 hrs, a 40% discount is applied (after 10 hrs )
Output the parking time and the parking fee only for the defined vehicle types as shown
in the examples.
Coding Requirements
Your program must meet the following coding requirements:
a) The parking hourly rates, the discount time thresholds (3 and 10), the discount rate
coefficients (0.2 and 0.4) have to be defined as constants
b) Use bool type ( defined in stdbool.h) to represent logical values trueand false
c) Your program must have at least the following user-defined functions
inputParkingTime (…)Prompt the user to enter the parking time. If the
entered value is not integer, round it up. Return the
obtained integer value
validateVechileType (…)Get the vehicle type as a parameter; validate vehicle
type; if the type is valid, the function returns true,
otherwise, it returns false. The function must not
print any messages on the screen
validateParkingTime(…)Get the parking time as a parameter; validate the
parking time; if the time is valid (0<time<=24), the
function returns 0; if it is ≤0 it returns -1; if it is > 24 it
returns 1. The function must not print any messages
on the screen
calculateParkingFee(…)the function returns the parking fee. The function must
not print any messages on the screen
showParkingFee(…)the function outputs the parking fee with the two
decimal point precision in a format shown in the
example
You need to define appropriate formal parameters and return type for each function.
Make sure that you do not use global variables.

Having been run, your program should produce output formatted as shown below
(the actual numbers may be different ):
Example1:
Enter your vehicle type (C, M or T): c
Enter parking time (hours): 2
Car 2 hrs parking fee: $7.00
Example2:
Enter your vehicle type (C, M or T): K
Wrong vehicle type
Example3:
Enter your vehicle type (C, M or T): t
Enter parking time (hours): -7
Wrong parking time
Example4:
Enter your vehicle type (C, M or T): T
Enter parking time (hours): 26
Parking time is limited to 24 hrs
Example5:
Enter your vehicle type (C, M or T): T
Enter parking time (hours): 4.2
Truck 5 hrs parking fee: $36.80
