So I'm making a seconds converter in C# for class. It's supposed to convert an integer entered into a textbox into appropriate units (seconds, minutes, hours, days) However, I can't for the life of me figure out what's causing these two errors.

1)You're writing outside the method
2)Your identation is fucked.

>>52862060
dog you can't store decimal things like you're trying to do in lines 24-32 into an int

(ie 3601 / 60 = 60.01666...)

just change the int to double

Never uses floats for math that needs to be accurate, they're mainly use for graphics pipeline because they are fast and don't need to be spot on.
Use longs or doubles.

ok i wrote this in C but i think it would be easy for you to convert this stuff?

int seconds,minutes,hours;
scanf("%d",&seconds);
minutes = seconds / 60;
hours = seconds / 3600;
printf("%d seconds,%d minutes,%d hours",seconds%60,minutes%60,hours%24);

Uhh guys, this code just looks disgusting and it was done by the worst way...

Think before you do something

Its not a hard mathematical challenge.
>>
Right now, if I type in 3600, it displays the proper value in hours. If I type in 3601, it gives the same output. Also, if I type in 86400 (seconds in a day) It just gives the time in hours, same with any number above that.

My point is that you're using the wrong language.

It's the required language for the intro course.
>>
>>52863852
I converted time this way.
Is there anything here I shouldn't do?
Help me improve /g/.
>>
>>52864376
instead of subtracting everything from seconds, just do int secs = seconds % 60;
>>
>>52864376
move the rest of the code into try, so you don't execute it if exception occurs, or alternatively put return in the end of the catch block
>>
>>52864452
So this then?
Any special reason for it? Or is it just considered more readable?

>>52864492
Ah yes, added a return, forgot to test that part.
Thanks.
>>
>>52864519
You don't need to assing anything to seconds past the conversion. For the real seconds initialize another variable and set it to seconds % 60;
>>
>>52861475
Holy fuck you're bad.
Please tell me you're not a student.

What the fuck did you just fucking say about me, you little bitch? I’ll have you know I declare all my variables at the top of my class in my IDEs, and I’ve been involved in numerous indie dev teams, and I have over 300 confirmed git pulls.
I am trained in office warfare and I’m the top developer in the entire cubicle farm. You are nothing to me but just another target. I will kill -9 you with precision the likes of which has never been seen before on this Earth, mark my fucking words.
You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of trolls across the darkweb and your IP is being traced right now so you better prepare for unsolicited dick pics, faggot. The storm that wipes out the pathetic little thing you call your social media account. You’re fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that's just with my guy fawkes mask.
Not only am I extensively trained in google-fu, but I have access to the entire backlog of Stack Overflow questions and I will use it to its full extent to wipe your miserable data off the face of the internet, you little shit. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your fucking tongue.
But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. I am legion. I do not forgive, I do not forget.
