How to repeat code after invalid data is entered

Question

I have an assignment to calculate the *parkingFee*, I'm having a hard time figuring out how to get this code to repeat after a invalid number (greater than 24 or less than 1) has been entered. The parking fee in a parking station is calculated on whole number of hours multiplied by the hourly rate of $2.50. A program is required to input and validate the hours to be between 1-24 inclusive. Calculate the parking fee given there is a maximum parking fee of $20.00. Output the hours parked and the parking fee (formatted to 2 decimal places)." Below you'll find the code that I'm having trouble with. Any help would be greatly appreciated. namespace _3PRB_Assignment_Part_1 { class Program { static void Main(string[] args) { /* Ryley Copeman * 29/08/2018 * Assignment parkingFee2*/ /* PSEUDOCODE */ /* HOURLY_RATE=2.5 * INPUT parkTime * parkFee = HOURLY_RATE * hours * OUTPUT parkFee */ decimal parkTime; // input - time in hour eg 1.5 for 1 and a half hours const decimal HOURLY_RATE = 2.50m; // HOURLY_RATE * INPUT parkTime = parkFee const decimal MAX_FEE = 20.00m; // MAX_FEE is set as a payment cap and ignores any extra charges incurred over 8 hours decimal parkFee; Console.WriteLine( "ParkingFee1 program developed by: Ryley Copeman" ); Console.WriteLine( "Please enter your total time parked in hours: Eg 1.5 or 3.0" ); parkTime = decimal.Parse(Console.ReadLine()); if (parkTime > 8) { Console.Write( "Total fee is $" + MAX_FEE); } else { parkFee = Math.Ceiling(parkTime) * HOURLY_RATE; Console.Write( "Parking Fee = $" + parkFee); } while (parkTime 24) // validate... //while (parkTime { Console.WriteLine( "Error – Park Time out of range" ); Console.WriteLine( "Enter - Park Time between 0 and 24 (HOURS):" ); parkTime = int .Parse(Console.ReadLine()); } } } }

hi, try below code namespace _3PRB_Assignment_Part_1 { class Program { static void Main( string [] args) { /* Ryley Copeman * 29/08/2018 * Assignment parkingFee2*/ /* PSEUDOCODE */ /* HOURLY_RATE=2.5 * INPUT parkTime * parkFee = HOURLY_RATE * hours * OUTPUT parkFee */ decimal parkTime; // input - time in hour eg 1.5 for 1 and a half hours const decimal HOURLY_RATE = 2.50m; // HOURLY_RATE * INPUT parkTime = parkFee const decimal MAX_FEE = 20.00m; // MAX_FEE is set as a payment cap and ignores any extra charges incurred over 8 hours decimal parkFee; Console.WriteLine( "ParkingFee1 program developed by: Ryley Copeman" ); Console.WriteLine( "Please enter your total time parked in hours: Eg 1.5 or 3.0" ); parkTime = decimal .Parse(Console.ReadLine()); if (parkTime 24) { Console.WriteLine( "Error – Park Time out of range" ); Console.WriteLine( "Enter - Park Time between 0 and 24 (HOURS):" ); parkTime = int .Parse(Console.ReadLine()); } else { if (parkTime > 8) { Console.Write( "Total fee is $" + MAX_FEE); } else { parkFee = Math.Ceiling(parkTime) * HOURLY_RATE; Console.Write( "Parking Fee = $" + parkFee); } } } } }
