Thread: Coding Problem-Help plz

HI, I'm new at this so I just need a little bit of assistance in this. I have done the source code and everything for this problem but can't do 1 thing. I need the program to end when I type 99 hours. Below is the problem and source code. I would appreciate anyone's help. thanks.

A parking garage charges a $2.00 minimum fee to park for up to 3 hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of 3 hours. The maximum charge is $10.00. (Hint: That means you dont have to calculate for anything over 18 hours.) Write a program that calculates and prints the parking charges for a number of cars. The user will enter the number of hours in hours and tenths of an hour. For example, the user will enter 4.5 for 4 hours and 30 minutes. The user will enter 99 hours to signal that the program should end.

Code:

#include <stdio.h>

int main()
{
	int car[3];
	double hours[3],  total_hours  = 0;
	double charge[3], total_charge = 0;
	int i;
	for ( i = 0; i < 3; ++i )
	  //car[i]=0;
	{
		printf("Enter car number? ");
		scanf("%d", &car[i]);

		printf("Enter hours parked? ");
		scanf("%lf", &hours[i]);

		if ( hours[i] < 3 )
		{
			charge[i] = 2.0;
		}
		else if ( hours[i] < 18 )
		{
			charge[i] = 2.0 + (hours[i] - 3.0) * 0.50;
		}
		else
		{
			charge[i] = 10.0;
		}

	  //printf("%1f%1f\n", "car" "hours" "charge");

	  //for (car=1; car < 3; ++car) {
		//printf("%d%1f%1f\n", car,hours,charge[hours]);
		//printf("%.2f%.2f\n", total_hours[hours],total_charge[charge]);

		total_hours = total_hours + hours[i];
		total_charge = total_charge + charge[i];
	}
  printf("%s  %s   %s\n", "car", "hours", "charge");

	for (i=0; i < 3; ++i) {
	 printf("%d    %.1f     %.2f\n", car[i], hours[i], charge[i]);
	}
	printf("    %.2f    %.2f\n", total_hours/*[hours]*/,total_charge/*[charge]*/);

	return 0;
}

I need the program to end when I type 99 hours...I dont know how to do that!

Thanks very much!

oh sorry, one more thing, how do I put this into my code?

Thanks alot!!!
