You can check value of <b> before moving on with division. case '/': if(b == 0) { cout << "Division by zero\n"; } else { // perform division } CrazySun03 you posted this question before, and some people already proposed answers, may I ask you why post another one? https://www.sololearn.com/Discuss/1679738/?ref=app

Alright then CrazySun03 , but if you still want to go with Exception way I might be able to help you a bit, which part of it that you find difficult? I'll see if I can shed a little light ...

Hey CrazySun03 I just paid a revisit to the Exception chapter, and strangely I feel the same with you, yes I think that chapter could use a little tweak. I did a test with division by zero, using `try ... catch` but I feel something is odd, errors such as division by zero doesn't seem to captured in `catch` block, I get no output instead XD. I will get back to you when I have better news to pass 👍

CrazySun03 I guess this article is related with, and may add an insight regarding division by zero error handling, I see the general voice there agree to check input before moving on with the operation. https://stackoverflow.com/questions/15277129/c-divide-by-zero

Ipang On the another question, i asked how to get (you can't divide by 0). On this question, I wanted to learn how to use "Exceptions", since I read the article and i didn't understand it very well I still don't know how Exceptions work, but your answer solved my problem

Ipang Well, i'm not very good at english, the C++ tutorial have translation, but the page of Exceptions doesn't. If you read it, you will se that it have 3 pages, i understand the first two perfectly, but i don't get why i should need 'try' and 'catch'. It seems like i can do the same with only 'throw'

Ipang Thank you very match. If wasn't for you, i wouldn't know that i can use an statement inside of a loop, (like if inside an switch case). Also thx for the article

Ipang I found how it works, If you use just throw, the program will terminate, and throw a terminate error, followed by a mesagge that you write If you use try and catch, you can now first, identify the error, and then trow a mesagge that you want, like "you can't do that - Error 99"

Eg: With only throw: int x = 2; int y = 1; if (y < x) { throw "Error 99"; } Output = Stopped Terminate called after throwing an instance of 'char const*' Error 99 -- If you use try and catch try { int x = 2 int y = 1 if ( y < x ) { throw 99 } catch (int x) cout << "You can't do that - Error << x; } Output: You can't do that - Error 99
