Bit Manipulation Basics AND OR XOR NOT Left Right Shift

📖 Scenario: Imagine you are working with a simple device that stores settings as bits in a number. Each bit can be turned on or off to control different features. You want to learn how to change these bits using basic bit operations.

🎯 Goal: You will create a small C program that uses bit manipulation operators: AND, OR, XOR, NOT, left shift, and right shift. You will see how these operators change the bits of numbers step-by-step.

📋 What You'll Learn

Create two integer variables with exact values

Create a variable to hold the result of bit operations

Use bitwise AND, OR, XOR, NOT, left shift, and right shift operators

Print the results of each operation

💡 Why This Matters

🌍 Real World

Bit manipulation is used in low-level programming, device control, and performance optimization where direct control of bits is needed.

💼 Career

Understanding bitwise operations is important for embedded systems developers, systems programmers, and anyone working with hardware or performance-critical code.

1

Create two integer variables

Create two integer variables called a and b with values 12 and 5 respectively.

DSA C

# Create two integer variables a and b with values 12 and 5
// Your code here

Hint

Use int a = 12; and int b = 5; to create the variables.

2

Create a variable for results

Create an integer variable called result and set it to 0.

DSA C

int a = 12;
int b = 5;
// Create an integer variable result and set it to 0
// Your code here

Hint

Use int result = 0; to create the variable.

3

Apply bitwise operations

Use the variables a and b to perform these bitwise operations and store each result in result: AND, OR, XOR, NOT of a, left shift a by 2, and right shift b by 1. Write one line for each operation.

DSA C

int a = 12;
int b = 5;
int result = 0;
// Perform bitwise AND of a and b and store in result
// Perform bitwise OR of a and b and store in result
// Perform bitwise XOR of a and b and store in result
// Perform bitwise NOT of a and store in result
// Perform left shift of a by 2 and store in result
// Perform right shift of b by 1 and store in result
// Your code here

Hint

Use & for AND, | for OR, ^ for XOR, ~ for NOT, << for left shift, and >> for right shift.

4

Print the results of each operation

Print the results of each bitwise operation in order: AND, OR, XOR, NOT of a, left shift a by 2, and right shift b by 1. Use printf with the format "%d\n" for each result.

DSA C

int a = 12;
int b = 5;
int result = 0;

result = a & b;  // AND
result = a | b;  // OR
result = a ^ b;  // XOR
result = ~a;     // NOT
result = a > 1; // Right shift

// Print the results of each operation below
// Your code here

Hint

Use printf("%d\n", result); after each operation to print the result on a new line.
