Manual time-c program

[aquilina]

i having a program that using function that automaticly detect time,date and day.. how can i only want to manually insert time? since the function including those 3 things... below my code

#include<stdio.h>
#include<ctype.h>
#include<time.h>
#include<stdlib.h>
#include <string.h>
#define size 80
#define MAX 100

I don't understand your problem.

In which part do you want to manually enter the time?
Where and how do you want to store it?
What do you want to do with that time?

I mean.. the date and day it will detect automatic from the system but the time we input manually.. but i already solved it.. but now i having problem how to arrange and calculate the fee for the parking.. because it sperated into weekday and weekend day... mon to friday different fee and saturday and sunday different fee.. how did the syntax looked like?
my latest code.. but i havent put the selection for the payment of fee...

How would you calculate the different fees on different days, without the computer?

Do that nice and slow, a few times, and you'll start seeing the pattern of the logic you need to add to the program. An if/else statement is all you need.

i still cannt get it once it coded.. take a look the table.. once it state the time from 9am to 5pm and the rest time is free.. i already getting confuse..

[Adak]

For dealing with days, since you have a tm already, maybe use this format, and get a day number.

%w Replaced by the weekday as a decimal number (0−6), where Sunday is 0. tm_wday

Either use 0-6 for the days of the week, or 1-7. Check which days get which numbers, because they don't always use Sunday as the lowest numbered day of the week.

Now the details need to be sorted out. What if a car parks on Friday at Noon, but stays until 2100 hrs 9pm. Charge the higher rate until 5 pm and free after that, right?

Some variables would be handy: mfFirstHalf, mfSecHalf, mfAfter1Hr, mfAfter24Hr

So a rate calculation includes calculating each of these, and then adding them up:

if(day is Monday-Friday && timeIn < 1700 hours, they pay the top row schedule, until 1700 (1700 minus timeIn). Say they arrived at Noon

  Covers the first hour,        leaving 4 hours * 2 to get the half hours
===========================================================
   mfFirstHalf + mfSecHalf + mfAfter1HrPerHalfHr 
fee=   .20     +   .50     +   (8*1.6)

And I'd make these non-free Rates into #defines and add them above main()

#define mfFirstHalf .20       //note: no semi-colon on these

The best way to stay clear on these things is to use VERY descriptive variable names. You have a more realistic version of this problem, which makes it more complex, but also, more fun to figure out.

ok this my latest code.. but i dont know how it gonna detect whether its saturday or sunday.. i only tried to code the payment.. now i still think about to diff the weekday and weekend fee
