    Question Wrong answer?

    i am a noob at C++

    i was doing this quiz

    Cprogramming.com - Tutorials - C++ Programming Quiz - Loops

    the first answer should be B.9, shouldn't it?? i executed this ..after inserting cout<<x<<endl;

    and the last value was 9...how come the answer is 10?

    thanks

    Note: This quiz question probably generates more email to the webmaster than any other single item on the site. Yes, the answer really is 10. If you don't understand why, think about it this way: what condition has to be true for the loop to stop running?

    It will be 10 as the final result.

    9 is smaller than 10 there fore it will be increased by 1 (x++)

    Now x = 10 therefore the loop will break

    What makes you think these 'people' are free ?
    If you always rely on others to answer your questions, you will never learn.
    Try giving it a thought first.
