trouble with looping
currently, i had write a program for testing my skill purpose.. but i got hang over this two part.

from the sourcecode above.. at the (add ticket) part, it supposed to be asking user to enter character Y/y or N/n. but i couldn't make it.. as user enter N/n, it still looping.. besides, the below part.. the formatted output is wish to show the ticket detail.. as like dis..
[1] Bank Negara [8] Nilai
[2] Bandar Tun Razak [9] Salak Selantan
[3] Bangi ...
[4] Serdang ...
...
.... . . .
Please Choose
Your destination : 4
Your Departure : 2
Your charges : RM 1.15
Add Ticket : Y
Your destination : 4
Your Departure : 8

Please enter RM 3.40 : 2.00
Please enter the remainder 1.40 : 2.00
Please collect your ticket ->
Bandar Tun Razak -> Serdang RM1.15

You remainder -> RM0.60
i had think hard.. and i have no idea on how to make the formatted output for the last part.. and also the character to add ticket. can anyone help to edit the code? and also give me some advice on why its not functioning.

i had think hard.. and i have no idea on how to make the formatted output for the last part.. and also the character to add ticket. can anyone help to edit the code? and also give me some advice on why its not functioning.
while(ticket != 0) ?
After input ticket will be Y y N n or some rubbish.
I don't know when do you want to stop looping, but I suppose when input is N or n
So write while(tolower(ticket) != 'n')
Why is ticket an integer? It should be char. I'm not familiar with stdio. Are you reading an int or char for input?

thx.. for the input reading for ticket i had found out the solution.. now the problems left is only the below part... how am i going to do the looping to show that what the destination and departure of the user entered if there are many.. like this part..
Please collect your ticket ->
Bandar Tun Razak -> Serdang RM1.15
Nilai -> Serdang RM2.25
You remainder -> RM0.60
i know that right after the "please collect your ticket ->" is a loop.. but i not sure how to gain the value from the above loop so that the program can show this part during the end.. all i done is the row is correct.. but the content is same.. like this..
Please collect your ticket ->
Bandar Tun Razak -> Serdang RM1.15
Bandar Tun Razak -> Serdang RM1.15
You remainder -> RM0.60
can anyone tell me what the parts or how to make it shown like the first part..
Please collect your ticket ->
Bandar Tun Razak -> Serdang RM1.15
Nilai -> Serdang RM2.25
You remainder -> RM0.60
