Here is the problem I am working on. It asks me to use the method CalculateCharges, but I don't fully understand how to do this or how it works. I would be grateful for any input.
Lab Problem III
A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours.
The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Develop a console program that calculate and displays the charges for each customer who parked a car in this garage yesterday.
You should input hours parked for each customer. The program should display the charge for the current customer. The program should use the method CalculateCharges to determine the charge for each customer.
The program should input as Double the hours parked by each customer. The program should continue asking for new customer until sentinel value is entered for hours parked.

I can't get it to stop looping
Module
modHrsPrkedSub Main()
Dim hrsPrk As Integer
Dim CalcCharges As DoubleConsole.Write("Enter Hours Parked, -1 to quit: ")
hrsPrk = Console.ReadLine()
While hrsPrk <> -1Console.WriteLine("Total Charges are {0:C}", CalcCharges)
CalcCharges = hrsPrk
End WhileConsole.Write("Enter Hours Parked, -1 to quit: ")
hrsPrk = Console.ReadLine()
End Sub ' MainEnd

I don't think anyone is going to do your homework for you (nor should they) . . .
that being said, the task is to write a method called 'CalculateCharges' that takes a double as an argument and returns a double as output.
I hope your course has covered syntax for conditional statements- if/else, select/case - as well as Console input/output, basic string formatting, and method declaration - sub/function.
Begin by writing 'psuedo-code' for the implementation of your method.

wait as second. . . step back. . . look at your previous program

I guess it says something about me personnally when people think I am being funny when I am being serious, and think I am being serious when I am trying to be funny
I will chaulk that up to the impersonal nature of the internet.
ok. . . we are going to do what is called a 'functional decomposition' and work our way through the problem. . .but you are going to do the work . . . I will ask you to do something and while what I may ask you to do will not make much sense, when we put it all together, it will. . .
Do you know the basic syntax for declaring a function
if you don't, review this link
I want you to write a function called CalculateCharges. CalculateCharges needs to take a double and return that exact same double. . . yeah I know it sounds useless but work with me here. . . the idea is lets build the program form first, then we will hash out the details.. . .
so I need to see that you can write CalculateCharges so that this code
dim dbl as double
dbl = CalculateCharges(12.121212)
Console.WriteLine(dbl)
outputs 12.121212
I wont go any further until I know that you can write that code

Ok, yes I can write a program that says “hello world” [funny]. At least you have a little humor. Procedure is where I start getting lost. Below is one of the programs I wrote for this problem. This is not complete, but it might give you an idea of where I’m at. I also tried to write this with a case select and a byval function, but I keep getting the errors in the calculateCharges part of the program
Module modHoursParkedSub Main()
Dim hrsParked As Double
Dim calculateCharges As Integer
Dim maximum As Integer
Dim minimum As Integer
maximum = 10
minimum = 2
Console.Write("Enter Hours Parked, -1 to quit: ")
hrsParked = Console.ReadLine()
While hrsParked <> -1
calculateCharges = ((hrsParked - 3) * 0.5) + 2
If hrsParked >= 16 Then
Console.WriteLine()
Console.WriteLine("New balance is {0:C}", maximum)
End If
If hrsParked < 4 The
Console.WriteLine() Console.WriteLine("New balance is {0:C}", minimum)
Else
Console.WriteLine()
Console.WriteLine("Cost for Hours Parked is", calculateCharges)
End If
' prompt user for input and read account number
Console.WriteLine()
Console.Write("Enter Hours Parked, -1 to quit: ")
hrsParked = Console.ReadLine()
End While
End Sub ' Main
End Module ' modHoursParked

Here's what you were wanting the first time around
Module
modPracticeHours Sub Main() Dim CalcCharges As Double Dim hrsPrk As DoubleConsole.Write("Enter Hours Parked, -1 to quit: ")
hrsPrk = Console.ReadLine()
While hrsPrk <> -1CalcCharges = hrsPrk
Console.WriteLine("Total Charges are {0:C}", CalcCharges)
Console.Write("Enter Hours Parked, -1 to quit: ")
hrsPrk = Console.ReadLine()
End While End Sub ' Main Function CalcCharges(ByVal hrsPrk As Double) As Double Return hrsPrk End FunctionEnd
Module ' modPracticeHoursknown2none

lets see what you have so far. . . give us an idea as to where you are lost.
Part of getting proper direction is letting somone know where you are.
Do you know how to declare a function method
Can you write a program that writes "Hello World" to the console and waits for the user to hit the [enter] key to exit
Its ok if you don't. . . we all started right there. At least the good ones did.
the bad ones started with dropping a label on a form, setting its text to "Hello World", and they think they are programming. . . but I digress. . . we are all here to help.
"Help me help you. . ."

best one
Is this what your looking for
Module
Module1 Sub Main() Dim dbl As Doubledbl = CalculateCharges(12.121212)
Console.WriteLine(dbl)
End Sub Function CalculateCharges(ByVal dbl As Double) As Double Return dbl End FunctionEnd

exactly . . .
now. .. lets shape the program. . .
write me a main program that asks me to insert the number of hours I parked. . .
it calls this simple CalculateCharges with my input and it writes out the output of caclulate charges . . .foir instance. . .
Pranathi
you are correct, a do loop is most appropriate
your function is supposed to be called CalculateCharges. . .
where are you calling your function like you were in the first program I had you write

I think I already did that. look at the above code and make sure. I’ve renamed things and I have a prompt for the user.
