if else

user056 (19)
So i am almost done with my program I just need to print the correct amount for the case that the entering and leaving dates are in different months. I am not sure if I can use an if statement for that? Thank you in advanced for all of the help!!

:D :D :D
And you said you know how to calculate on paper.
:D :D :D

If I leave car for 2 years, I will pay only $8.00. It's very cheap.

P.S.
It means you can't use if-else. You need to calculate fee like in math. Using math formulas. Where time is x.

I do know how to do the math! What I do not know is how to put it in code. I also understand that it only works for 24hrs that is why I was asking for help so it will be in a different month or for more than 1 day. I would really appreciate any guidance with this. Thank you

my question.
atoi( dateStr.substr( 0, 2 ).c_str() )
do you know what that does?
user056 (19)
Converts string to integer
Shinigami (309)
Show to me how you do it on paper.
As I said you need a function like
f()=2d+3m-2
d - days; m - mins.
user056 (19)
Okay, think I got it thank you so much for all of the help:)
Shinigami (309)
It is good that you understand :D
