Assignment Help Needed, First year uni C programming assignment, any help appreciated
I need some help for this task I have to have in soon. I'm writing the code using Quincy and have got all the basis down; but I'm just getting stuck on little fiddly bits which I'm unfamiliar with. EG local and global variables, calling and returning functions, if/else functions, etc.
Any help is appreciated.
Thanks
Task:
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 type' when 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. Therefore, one hour minimum charge is applied. The program should validate the input time. Display a message 'Wrong parking time when parking time is invalid.
c) Calculates the amount charged based upon the following rates:
car - $5p/h, motorbike - $2p/h, truck - $10p/h
However, if parking time is longer than 4hrs, after that a 25% discount rate is applied ( after 4hrs ). If parking time is longer than 12hrs, after that 50% discount is applied ( to all period after 12hrs ).
d) Output the parking time and the parking fee
Code so far:
Code:

#include <stdbool.h>
#define CAR 5.0
#define MOTORBIKE 2.0
#define TRUCK 10.0
#define DISCOUNT1 0.25
#define DISCOUNT2 0.50
#define TIME1 4
#define TIME2 12
