...yes Banfa ...agree entirely with you... one of my more pathetic solutions especially as it was not even C. The David H method is brief and simple but haven`t seen that NULL form before. However I assume alas it is also C++. Will study your stream method more closely in due course. Thanks.

3. HEX to DEC    bytes.com

Start with something basic. Write a conversion function whose input is a char-pointer to a HEX-ASCII string with optional leading whitespace (that is, it is terminated by the first non-HEX-ASCII character). This function returns an updated char-pointer value (that points to the character that terminated the HEX-ASCII string) and the integer value corresponding to the HEX-ASCII string. How should your function ...

I have a problem converting from "string of hex" to "string of dec" and vice versa. for example, i want to convert : "20000000000000000"hex to "36893488147419103232"dec or "36893488147419103232"dec to "20000000000000000"hex notice that the number is larger than maximum value of 64-bit int (long long int). that's why i can't use a variable as a temporary storage of the real value. i ...

For this reason, simplest hex print function would always use "&" and bit shifting. 2) Characters formed by adding "0" to low order bits and correcting for A-F. 3) Simplest loop processes low order byte first - this means value will be printed in reverse. 4) Simple ...
