Week 1 exercise 24

[Piks]

Hi,

I'm having problems with week  1  exercise 24.

I don't understand how to indicate on the code that when the year can be divided by 100 it must also be divisible by 400.

The link to my work is here: https://tmc.mooc.fi/mooc/paste/wVZWT-IoGedVayk84FKRIQ

 

Help will be much appreciated.

Best regards,

Piks

Hello,

First of all that is exercise 21, not 24. Please edit the title.

You can find the algorithm of the Leap year on Wikipedia:

if (year is not exactly divisible by 4) then (it is a common year)
else
if (year is not exactly divisible by 100) then (it is a leap year)
else
if (year is not exactly divisible by 400) then (it is a common year)
else (it is a leap year)

So, you can use the following formula to find out if the year is or isn't divisible with a certain number:

year%100 == 0  //is divisible to 100

year%100 != 0 // isn't divisible to 100

Kind regards,

You algorithm is wrong.  The correct one is: if (year is divisible with 4 but it's not divisible with 100, or is divisible with 400) then it's a leap year.

Hei,

Vuosi on karkausvuosi seuraavien ehtojen mukaan:

Vuosi on jaollinen neljällä ja vuosi ei ole jaollinen sadalla. 

TAI

Vuosi on jaollinen neljällä, sadalla ja neljälläsadalla. Tässä oikeastaan riittää tarkastaa onko vuosi jaollinen neljälläsadalla sillä 4 * 100 = 400 joka väistämättä tarkoittaa vuoden olevan jaollinen neljällä ja sadalla jos vuosi on jaollinen neljälläsadalla.

Ja ehdot voit toteuttaa käyttäen && merkintää ja tai ehdot käyttäen || merkintää, muista kuitenkin käyttää sulkuja tarvittaessa.

Ystävällisin terveisin,

Joni
