right shift a packBCD string

[roswel]

Hi,

I have this BCD string: 890123...78FFF and need to right shift by say 3 nibbles, resulting in: FFF890123...78
length is fixed, number of 'f' nibbles are varying.

appreciate any algorithm/tips on this. thanks.

See:

http://www.cplusplus.com/reference/string/string/?kw=string

for(int i = 0; i < f; ++i)
{
  char ch = bcd_str.back();
  bcd_str.pop_back();
  bcd_str.insert(0, ch);
}

we're nibble shifting, so I wonder if above the code will work, which is char shifting (i.e a byte). thanks for response anyways.
