    Default type qualifiers ignored

    Hi

    I got a "Warnung: type qualifiers ignored on cast result type [-Wignored-qualifiers]"

    response.data is unsigned char

    Qt Code:
    1. Response response = signHash(pin, hash);
    2.  
    3. for (uint i = 0; i < response.length; i++)
    4. ba[i] = (const char)response.data[i];
    To copy to clipboard, switch view to plain text mode 

    Can i simply remove "(const char)" for same result?

    lg Chris

    Yes. The thing is that the `const` part in the cast is superfluous. If the `data[i]` us `unsigned char` then you can simply remove the cast altogether.
