Why
A bit wise AND operates on the bit level and uses the following Boolean truth table:
TRUE AND TRUE = TRUE
TRUE AND FALSE = FALSE
FALSE AND FALSE = FALSE
When the binary value for a (0110) and the binary value for b (1010) are AND’ed together we get the binary value of 0010:
int a = 0 1 1 0
int b = 1 0 1 0 &
---------
int c = 0 0 1 0
The bit wise AND does not change the value of the original values unless specifically assigned to using the bit wise assignment compound operator &=:
