Ex: write a C program to perform bitwise AND operation of two intiger's. How to write C Program to perform AND operation of two intiger's. C program to perform AND operation of two intiger's.

Input from user:

a=5 , b=15;

Expected Output:

After performing AND operation the output is: 5

  Logic to perform AND operation of the two intiger's :

First you need to know how  AND operator works.

• The result of AND is 1 only if both bits are 1. Otherwise result is 0.

1. We take two intiger numbers a=5 and b=15.

2. The binary representation  of  a & b is:

       a=      0000 0101
       b=      0000 1111
---------------------------------
  a&b=      0000 0101 =5

3. After performing AND operation 8 bit binary representation is 0000 0101 which is 5 in decimal.

4. So output of the program is  5.

  C program using bitwise AND (&):

#include<stdio.h>
void main()
{
int a=5, b=15;

printf("After performing AND operation the output is:%d",a&b);

}

Above program shows the following output:

Bitwise Operators In C

Definition: A bitwise operator is an operator used to perform bitwise operations on bit patterns or binary numerals that involve the manipulation of individual bits.
Bitwise operators are used in communication stack.

Operations can be performed on a bit level using bitwise operators. We use bitwise operators to manipulate data  at its lowest bit level.bitwise operators works on each bit of the data.

There are six bitwise operators are in C programming:

Above table shows six bitwise operators in C programming:



1. Bitwise AND(&):

It takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1.

[It is used to check perticular bit of data is ON(1) or OFF (0).]

Suppose we will take two intiger variables a & b, where a=9 and b=10.

8 bit binary representation of a & b is...

a= 0000 1001
b= 0000 1010

It will be evaluated as- 

So a & b is evaluated as 0000 1000 which is 8 in decimal.




2. Bitwise OR(|):

It takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1.

[ It is commonly used to set flag bit values.]

Suppose we will take two intiger variables a and b, where  a=4 and b=11.

8 bit binary representation of a | b is...

a= 0000 0100
b= 0000 1011

It  is evaluated as-

So a | b is evaluated as 0000 1111 which is 15 in decimal.




3. Bitwise XOR(^):

It takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different.

Suppose we will take two intiger variables a and b, where a=6 and b=13.

8 bit binary representation of  a^b is....

a= 0000 0110
b= 0000 1101

It is evaluated as-

So a^b is evaluated as 0000 1011 which is 11 in decimal.

4. Bitwise Complement or NOT (~):

It takes one number and inverts all bits of it. Means it  sets bit value 1 only if corresponding bit of operand is 0.

Suppose we take intiger variable a, where a=4.

8 bit binary representation of a is-

a= 0000 0100

It is evaluated as-

So a~ is  evaluated as 1111 1011 which is 124 in decimal.

5. Bitwise left shift(<<):

It takes two numbers and left shift the bits of the first operand, the second operand decides the number of places to shift.

Suppose we take an intiger variable a=15.

8 bit binary representation of a is-

a= 0000 1111

It is evaluated as-

Here,  ex: a<<1 means it shifts  bit one times to left which is 30  in decimal. another one example is a<<2 means it shifts bit two times to left which is 60 in decimal.
Left shifting of bit causes insertion of zero from right.




6. Bitwise right shift (>>):

It take two numbers and right shift the bits of the first operand, the second operand decides the number of places to shift.

Suppose we take intiger variable a=15.

8 bit binary representation of a is-

a= 0000 1111

It is evaluated as-

Here, ex: a>>1 means it shifts bit one time to right which is 7 in decimal. another one example is a>>2 means it shifts bit two time to right which is 3 in decimals.

C program to print given number is even or odd using bitwise AND operator

Ex: How to find given number is even or odd using bitwise AND operator. C program to print given number is even or odd using bitwise AND operator. What is the logic to print given number is even or odd using bitwise  operator.

Input from user:

Enter the number 

5

Expected Output:

Given number is Odd

   Logic to print given number is even or odd using bitwise operator:

Firstly you need to know how bitwise AND operator works. We can use bitwise AND (&) operator to check given number is even or odd. For example, consider one odd number ( 5 ).  So binary of 5(0101), (5 & 1 = 1). Means least significant of every odd number is 1. Therefore (Odd number & 1) is  always one and also (Even number & 1) is zero.

In Below program we will use bitwise AND operator to check whether given number is even or odd.  [if(no & 1)] means if this condition is true then number is odd otherwise number is even. Because List significant Bit(LSB) of every odd number is 1 and even number is 0. Which is shown above.

   Program to print given number is even or odd using bitwise AND operator:

#include<stdio.h>

void main()

{

int no;

printf("Enter the number\n");

scanf("%d",&no);

if(no & 1)

printf("Given number is Odd\n");

else

printf("Given number is Even\n");

}

Above program shows the following output:
