Demo of Left Shift Operator

The value of b2:=84

Explanation: The binary representation of 42 in 8 bits.

bits b7 b6 b5 b4 b3 b2 b1 b0

b1(42) 0 0 1 0 1 0 1 0

In the left, shifting bits are shifted towards left as: bit b0 moves to b1, b1 to b2 and so on . A zero is

inserted at the b0 position. After shifting bits of b1 once, the resultant bits patterns will be as follows:

bits b7 b6 b5 b4 b3 b2 b1 b0

b1(84) 0 1 0 1 0 1 0 0

NOTE: Shifting the bits left once multiplies the number by 2, while shifting the bits left by n number of times

multiplies ...
