(#47) What happens when you divide an integer by a variable with a value of 0?

o Compiler Error
o Compiles and Runs
o Runtime Exception

Doesn't the answer depend on information that is not presented in the question, namely the type of the second variable?

Thanks,

I think there is a little bit of an assumption here that because the variable has the value 0 it is either int, byte, short, or char. Any of these will throw a runtime error.

Where I think this question gets a little off is that you can do the following.

double a = 0;
5/a;

and you don't get a compile or runtime error.

If u did't assume that the Data type of the second variable integer then only it will give the runtime Airthmetic Exception

Otherwise if one of the value is float/double then it will Run succesfully
