c bit operations code example

Example 1: bitwise operator

12 = 00001100 (In Binary)
25 = 00011001 (In Binary)

Bitwise XOR Operation of 12 and 25
  00001100
^ 00011001
  ________
  00010101  = 21 (In decimal)

Example 2: opération bit à bit c

unsigned a = 0xF0F0;
   unsigned b = 0x00FF;
   unsigned c = a & b; /* c == 0000000011110000 soit 0x00F0 */
