Hi Shena,

check the following GREAT links:

Plus read the following as well:

Shift and Bitwise operators are used to manipulate data at bit level.

Shift operators should be used only with operands of type int or long, though they can also be used with other integral types. Shift operators always return a result of type INT or LONG.

Positive integer0..0 110012
Negative integer1..1 1100-4

Negative integer1..1 1100-4
Signed right-shift1..1 1110-2
unsigned right-shift0..1 11102147483646
Left-shift1..1 1000-8

With the unsigned right-shift operator (>>> and the left shift operator, the new bits are always set to 0.

The result of ~x will always be the value ((-x) -1)

Gitesh
