Question

I’m trying to catch a divide by 0 arithmetic exception in my code but it looks like NSException is not catching that and program is terminating with message exc_arthimetic error. What is the way to catch the exception

     @try {

         int k;

         printf("please enter k value \n");
         scanf("%i",&k);

         int j=1;

         // testing division 1/0 condition
         int i=j/k;
         NSLog(@" value of i= %i",i);
     }

     @catch (NSException *exception) {
         NSLog(@"exception is = %@  reason is %@",[exception name],[exception reason]);
     }
     @finally {
         NSLog(@"inside finally");
     }


     NSLog(@" last line");

Answer 1

exc_arthimetic is not an exception but rather a signal sent by the OS. I would suggest checking that the denominator is not zero before trying to divide.

In order to catch this signal is more complicated and likely not worth the effort.

Take a look at
