    Hi All

    C doesn't warn on overflows.

    And it's probably showing up right because you're printing it with printf() using %d instead of %u which means printf() is just reading it as a signed int instead of unsigned. Try using the correct format specifier (%u) for unsigned int and you should see something different.
    If you understand what you're doing, you're not learning anything.
