C 语言中的优先级

先看一段代码：

/*********************************************************************
 * @fn      bdAddr2Str
 *
 * @brief   Convert Bluetooth address to string. Only needed when
 *          LCD display is used.
 *
 * @return  none
 */
char *bdAddr2Str( uint8_t *pAddr )//ownMacAdd[6]
{
#define B_ADDR_STR_LEN    15

  uint8_t     i;
  char        hex[] = "0123456789ABCDEF";
  static char str[B_ADDR_STR_LEN];
  char        *pStr = str;

  *pStr++ = '0';
  *pStr++ = 'x';

  // Start from end of addr
  pAddr += B_ADDR_LEN;

  for ( i = B_ADDR_LEN; i > 0; i-- )
  {
    *pStr++ = hex[*--pAddr >> 4];
    *pStr++ = hex[*pAddr & 0x0F];
  }

  *pStr = 0;

  return str;
}

看到这段代码，我首先就想到了优先级。经过测试得出优先级为：

*优先级大于 --、++的优先级。
