print BCD value with itoa

Question

I need to print on screen a variable value that is encoded in BCD.

Do you know whether is possible to print it on screen by using itoa?

If that is possible, how to do that?

Answer 1

No, itoa will not help. You want to look at the hexadecimal representation, so use hex like in cout << hex << n << endl;

Note: BCD codes the digits as 4-bit-sequences 0000 to 1001, which in hexadecimal are 0 to 9. So 23 as BCD would be 0010 0011 bitwise, or in fact as 8bit integer it would be 35, so converting this to a string will not be of much use.
