C Parking Ticket System

This assignment presents a C program designed to simulate a parking ticket system. The program prompts the user to input the parking duration in hours and minutes. It then calculates the parking charges based on a tiered system: free for less than 20 minutes, RM2 for 1-3 hours (with additional RM1 for each extra hour), and RM5 for more than 3 hours. The program further simulates the payment process, accepting only RM1, RM5, and RM10 notes, and providing feedback on the remaining balance. Finally, it offers the option to print a receipt. The code includes input validation to ensure the user enters valid note denominations. The solution demonstrates fundamental C programming concepts such as conditional statements, loops, input/output operations, and basic error handling.
