Because the while loop can't complete, that line is unreachable.

Could you please tell us the source of these questions of yours Shiaber? Usually good Mock exams have fairly detailed explanations of their answers.
Thanks

Hi Guys...I understand that the code is not compiling due to the unreachable statement at line 20 But I am not getting that why compiler is not giving any error on line 14. When we are repeating the same statement on Line 14 as on Line 13. Please Help

Regards
Swapnil

Hi Joshua:
I got that line 20. But I am asking that why the code is not giving any error on line 14 when we are repeating the statement of line 13.
13. assert false;
14. assert false; // here it should give compilation error???

Hi Swapnil,
Repeating the statements doesn't result in error.
For ex:

will not give any compilation error.
The first statement is executed followed by second one.

Hi Swapnil,
I think I got your question now.
The compiler does not give error because the compiler is not smart enough to know whether assertion will be enabled at run time.
Note that assertion are disabled by default.
Hence no error at line 14.
Sorry for my previous post.

Regards,
Joshua.
