C Programming - Bitwise Operators - Discussion

I explain in simple manner

bit wise & truth table
=========================
a b z
=========================
0 0 0
1 0 0
1 1 1
0 1 0
==========================
only one condition satisfyied foe on bit excpt bit value is off position

If you want to off the bit means u want to make it ZERO it is possible in only & condition because
in & if 1 1 o/p-1
else 0

Please explain how to convert hexa decimal into binary.

Bitwise operator is more easily been applied than the logical operator.

Thanks ramya.

Turn off operator in bitwise operators is and because it turns 1&0 and 0&1 into turn off(that is o). |(OR) bitwise turns preceeded operations into turn on(that is 1).

Hence AND IS turn off operator.

I have 1 doubt please tell me how to find the status of a bit ie char s[50];

Then write a c program to find the status of 170th bit.

Sorry, I know this is an outdated thread... But just saw Mr.Gaurav's doubt to be one which I had a days back.
Here is a simple explanation, correct me if am wrong.

@Saurav

Its like && and || are logical operators, evaluting true statements.
Eg:
Sachin && Sehwag opens batting, It returns true(1) only if both the guys are present to open the game. Else False(0)

Sachin || Sehwag, return true(1), if either Sachin or Sehwag accompanied by someone else opens the game. Else false(0)

& and | are bitwise operators, High and Low
AND, OR gates truth table pretty much explains it.
Eg:
2 & 3 (AND)
010
&
011
------
010

2 | 3 (OR)
010
|
011
------
011

Bitwise operators can be predominantely found in Embedded design, to find the status (ON or OFF) of a bit in a system.


Hope this explains...

Cheers...

How to work bitwise ?

Please explain about bitwise operator?
