    qWarning() << str;

Hi,
If you want use Qt, you can use above code.
In C++ you must use library can handle big data like biginteger(https://mattmccutchen.net/bigint/) or gmp(http://gmplib.org/).
So, you can convert your number to HEX with this tutorial link http://www.permadi.com/tutorial/numDecToHex/

THank you for your attention.
