Bitwise operators

Bit-wise operators work after the given operands are converted to their binary equivalent value.

Learning Objectives

  • Understanding the concept of bit-wise operators with the help of bit-wise and & and bit-wise or | operators.

Source Code

TC++ #1743


Source Code

Run Output


Code Understanding

here the value of x which is 81 and y which is 61 in this example will be converted to binary equivalents
Now match vertically the columns bit-wise. Mark a 1 where 1 is present in both top and bottom row. This will yield
Now convert this value back to decimal. This will result in a value of 17.

In this case instead of check for 1 present in both top and bottom row, check for 1 present in any of the row. This will yield.
Converting this to decimal will yield 125.


The list of bit-wise operators is as follows:
& – Bit-wise AND
| – Bit-wise OR (inclusive OR)
^ – Bit-wise exclusive OR
~ – Bit-wise unary complement (Bit inversion)
<< – Bit-wise left shift
>> – Bit-wise right shift

You can try other combinations of bit-wise arithmetic operations.

<< and >> are visibly similar to IO insertion and IO extraction symbols used with cout and cin respectively, but they operate as bit-wise operators when operands on both side are mathematical numbers.
