    Mmm, the first thing the C compiler usually does is remove comments, so a source file without comments is not really much different.

    But some program...
    not in C, if i remove the comment
    it cannot run.....
    how come?

    Depends on your OS and compiler - which do you have
    I use Linux, and gcc compile...
    but does it really count on the OS or compiler?
    I thought there will be a command or method to do with it...

    comments have _nothing_ to do with code. Comments are there solely for you by you. The preprocessor strips all comments prior to the syntax check.

    If you strip comments and can't compile, you either stripped too much, or too little and diddled the some of the code itself.
    It is not the spoon that bends, it is you who bends around the spoon.

    Ok, let's forget about the comments one.

    So that means i cannot read in a HardDisk Serial Number?

    Or there still exist someother way to do it?

    Sorry, we kind of got off topic there. Any more questions Kam? Everything working properly?
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
