    Plz Tell me how to Read Characters like Key UP, Key Down

    Please Help me:
    I am creating a project; where I need a line text editor
    Here,
    I am using:
    int a=bioskey();
    however It returns different values 4 different keys. So I 've to check the value of bioskey() for every key. Is there any simpler procedure?
    Plz reply fast

    You mean without checking ALL keys? No.
    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;
    }

    Why don't you just scan for the ASCII values of up, down, etc..
    The world is waiting. I must leave you now.

    I think I understand what you are trying to say.
    If you meant that you are sick and tired of searching the value for every key and want an easier method, there are several options:

    some solutions:

    -go find a site that shows a conversion chart between the keys and the codes (ASCII, scan codes, bios codes?, etcetera)...

    or

    -you can just do a simple loop that will output a simple conversion chart or list between the keys and the codes

    by the way, you are using bios.h, right?
    think only with code.
    write only with source.
