c++ bit shift wrap code example

Example 1: c++ bit shift wrap

uint8_t a = 124;
uint8_t aShifted = leftBitshiftWrap(a,2);

uint8_t leftBitshiftWrap_uint8_t(uint8_t val, uint8_t amt){
  return (val << amt) | (val >> (8-amt));
}

Example 2: get bitshift to wrap c++

//Rotating integers are done as follows
letter = ((unsigned char)letter >> 1) | (letter << 7);
