When you 'OR' 2 char literals the chars are first converted to their unicode values. In the case of 'a' 'b' and 'c' these unicode values are 97 98 and 99 respectively. The least significant byte of these values in binary is: 97 -> 01100001 98 -> 01100010 99 -> 01100011 It's now easy to see that 'a' | 'b' is 01100011 and if you then OR this result with 'c' you also get 01100011 or 99 decimal. Converting 99 back to a character gives 'c'. Consequently following through the 'switch' statement the output of that code is: case D | case d
