Bitwise Operators In C, Exercises and Examples with Solution

In the C Programming language, 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.

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.

There are six bitwise operators are in C programming:

Above table shows six bitwise operators used in C programming language.

Bitwise Operators In C:

Bitwise AND
Bitwise OR
Bitwise XOR
Bitwise Complement
Bitwise left shift
Bitwise right shift

For more details:- bitwise operators .

Bitwise operators in C exercise examples:

1. Write a C program which perform bitwise AND operation.

2. Write a C program which perform bitwise OR operation.

3. Write a C program which perform bitwise XOR operation.

4. Write a C program which perform bitwise Compliment(~) operation.

5. Write a C program which perform bitwise left-shift(<<) operation.

6. Write a C program which perform bitwise right-shift(>>) operation.

7. C program to print given number is even or odd using bitwise operators.

C Program To Print Square star Pattern

Ex: Write a C Program To Print Square star Pattern. How to write a C Program To Print Square star Pattern. C Program To Print Square star Pattern.

Input from user:

Enter number: 5

Expected output:

* * * * *

Step by step logic to print square star pattern:

1. First accept input(number) from user which shows how many rows and column's do you want to print.

2. After that use one external for loop which will interate from 0 to no-1 and it shows rows in your square pattern:

for(i=0;i<no;i++)

3. Then use one another for loop inside the above for loop which prints the number of columns:

for(j=0;j<no;j++)

4. Inside the inner loop means inside the second for loop print * with one space like this:

printf("* ");

5. After that use \n for new line(new row).

Program to print sqaure star pattern:

#include<stdio.h>
void main()
{
int i,j,no;

printf("Enter the number:\n");
scanf("%d",&no);

for(i=0;i<no;i++)
{
for(j=0;j<no;j++)
{
printf("* ");
}
printf("\n");
}
}

Above Program show's the following output:

C Program To Print inverted Pyramid star pattern

Ex: Write a C Program To Print inverted Pyramid star pattern. How to write a C Program To Print inverted Pyramid star pattern. C Program To Print inverted Pyramid star pattern.

Input from user:

Enter the number:

Expected output:

*******

******

*****

****

***

Step by step logic of the given program:

1. Accept input(number) from user which shows number of rows, declare variable say no.

2. Run one outer loop from 1 to no:

for(i=1;i<=no;i++)

3. To print spaces run another for loop from 1 to i-1:

for(j=1;j<i;j++)

printf(" ");

4. To print star use another one inner for loop from i to no:

for(k=i;k<=no;k++)

printf(" *");

5. For new row, move to next line using \n.

Program to print inverted pyramid star pattern:

#include<stdio.h>
void main()
{
int no,i,j,k;

printf("Enter the no\n");
scanf("%d",&no);

for(i=1;i<=no;i++)
{
for(j=1;j<i;j++)
printf(" ");

for(k=i;k<=no;k++)
printf(" *");

printf("\n");
}

}

Above program shows the following output:

C Program To Print Given Number Is Even or Odd

EX: What is logic to print given number is even or odd. C program to print given number is even or odd. how to print given number is even or odd.

Logic to print given number is even or odd:

1. In this Program we will take number from user using no variable.

2. Next we will check it is even or odd using the (no%2==0).

3. Means if no is complete divisible by 2 then it is even otherwise number is odd.

4. Display this output using input/output function.
