parking garage

[Jenkinz]

Im trying to make ap arking garage that will tell me how much customers owe me based on the number of hours they have parked in my garage, i have an array of people that hold am onthly pass, and the user ahs to tell me their ticket number. If their ticket number matches the list of passes they will not owe anything, o else i mus calculate how much they owe me. To calculate how much the client owes me i need a program that will be based on a 24 horu clock i.e 00:00 is 12:00 midnight, 13:30 is 1:30 in the afternoon, and will calculate the time in the garage at $1.00/per half an hour with a 10.00$ daily maximum, this is what i have so far and it doesn't seem to be co-operating any help would be appreciated.

code:

var pass : array 1 .. 10 of int := init (1234, 4321, 2345, 5432, 3456, 6543, 4567, 7654, 5678, 8765) var time1 : int var time2 : int var answer : int for i : 1 .. 10     var found : boolean := false     if pass (i) = answer then         found := true     end if     put "what is your pass number?"     get answer     if found = true then         put "You owe no money, you may proceed."     else         put "You are not a member please enter the time you arrived"         get time1         put "please enter the time you left"         get time2     end if end for

how would i be able to make it so that this program would be able to calculate minutes as well, so if the user entered at 2, and left at 2:25?

code:

var number : string var list : array 1 .. 10 of string := init ("1234", "4321", "2345", "5432", "3456", "6543", "4567", "7654", "5678", "8765") var found : boolean := false var total : real var time_in : real var time_out : real put "please enter your number" get number for i : 1 .. 10     if list (i) = number             then         found := true     end if end for if found = true         then     put "thank you for coming" end if if found = false         then     put "you have not registered with the garage when did you enter?"     get time_in     put "what time did you leave?"     get time_out     total := (time_out - time_in) * 1 * 2/30 end if if found = true         then     total := 0 end if if total >= 10.00 then total := 10.00 end if put "this is your total" put total : 3 : 2

You could ask the user how much time they have been there total (hours and minutes). Or you would have to set it up so that the program recognizes the difference between AM and PM time and then calculates the difference between the times. The way it is set up now you get negative amounts if you enter 10 and 1.

How about using 24-hour time?

yea, thats exactly what i was trying to do, but for some reason it wasn't going along, I.E when you said you entered at 13, and left at 14.50, it would come up as something such as your charge would be .60

What you need to realize is you are trying to turn a decimal number into time. What you aren't doing is seeing that from 1:00 to 2:30 will give you a decimal number of 1.3.

Take a good look at 1.3 - what can you get from that.

The 1 represents hours, the .3 represents minutes, correct? So how do you incorporate this into costs and whatnot, and how do you extract the values?

You can divise a formula to fit into 1 variable, but lets split this up a bit.

Hours:

pseudo:

Hours := Floor (endTime - startTime)

Minutes:

pseudo:

Minutes := (endTime - startTime) - Hours

That is how you would extract time from a real number. The rest is up to you, afterall it is your assignment .

Hint: You will need to convert your minutes into a whole number, then divide them by a certain time factor.
