parking lot game

[hahahaha]

The sign on the attendant’s booth at the XYZ parking lot is


XYZ VISITOR PARKING


Cars:
First 2 hours Free
Next 3 hours 0.50/hour
Next 10 hours .25/hour
Trucks:
First 1 hour Free
Next 2 hours 1.00/hours
Next 12 hours 0.75/hour
Senior Citizens: Free of charge

Write a program that will accept as input a one-character designator (C, T or S)
Followed by two military numbers in range of 0600-2200 (6:00 A.M to 10:00 P.M). The program should
Then compute the appropriate charge and the round up time that car was parked.
The output should be printed for each vehicle , arrival time, departure time and cost. Your program should also provide a summer at the end of each day indicating total cars, trucks, and senior , time and fees. Your program should have loop which ends with ^Z.


this is the question. im new to C so i didnt use case and breaks.. but i used if and else. my qustion in when i compile it deos not show anything!! why is that??

#include <stdio.h>
 
int main(void)
{
  char type;
  int t, in, out;
  int total,truck=0,senior=0,cars=0;
  
   
 do
 {
     while(("%c %d %d", &type, &in, &out)!=EOF)
       {
     printf("car type:\n\n");
     scanf("%c", &type);
     printf("in time:\n\n");
     scanf("%lf", &in);
     printf("out time:\n\n");
     scanf("%lf", &out);
  
  
 t=((in-out)/100);
 
 if (type=='C')
 {
   cars++;
   if (t<=2)
    total= 0;
   else if (t<=5)
   total=(t-2)*0.5;
   else
   total =((t-5)*0.25);
 }
 
 else if (type=='T')
 {
    truck++;
    if (t<=1)
     total=0;
    else if (t<=3)
    total= ((t-1)*1);
    else
    total= ((t-1)*0.75);
  }
  else if (type=='S')
  {
    senior++;
    total=0;
     }
   
  printf("youcame in @:%d", in);
  printf("you left @: %d", out);
  printf("your cost is: %lf", total);
  
   }
   
      
     
   return 0;
 }

ps im suppose to ask "if you want to conitue". if anybody could help me with that that would be awsome!!!
thanks

     while(("%c %d %d", &type, &in, &out)!=EOF)

What is that supposed to be? (scanf probably)How about instead you do something like:

do
{
    prompt for input
    get input
    if input is valid
        process input
    if input means to quit
        set quit to true
while quit is not true

The sign

I'm going to assume you are visually impaired... because only a blind person needs such a big ugly font.

What do in time and out time represent? minutes? Hours?
What if someone checks in at 23:00 and checks out at 02:00 the next day?

You have an unterminated do loop in there... Your while loop doesn't make a lot of sense. I'd be amazed if your code even compilers. You need to read up on loops in your textbooks or through a good online tutorial (Google is your friend).

This is a very simple exercise, I can do it in just under 50 lines...
