Took me a while to figure out but here is the code

it is highly recommended that you learn a how to convert decimal s to hexadecimals the mathematical way before attempting to create an algorithm
please note: this algorithm uses a lookup table to identify the hex character and so gives you more control and allows you to see what is going on under the hood. other examples ive seen use the .toString(16) to convert to hexadecimal so you dont really see what is happening.

hex numbers are prefixed with 0x, for example 0xbc5+0xa8

ok, thanks, but how can I get the syntax in order to have the sum per ex:
1CEC + BEC = 28D8
i have tried some syntax that is written like this : cout << "The sum is "<<std::hex<< a + b << "." << endl; but the result is only 28 not 28D8
thanks
