Left shift and right shift in C - Mini Project: Build & Apply

Left shift and right shift

📖 Scenario: You are working with a simple device that uses bits to store information. You want to learn how to move bits left and right to change numbers quickly.

🎯 Goal: You will create a program that uses left shift and right shift operators to move bits in a number and see the results.

📋 What You'll Learn

Create an integer variable with a specific value

Create variables for the number of positions to shift

Use left shift operator to shift bits to the left

Use right shift operator to shift bits to the right

Print the results of the shifts

💡 Why This Matters

🌍 Real World

Bit shifting is used in low-level programming, such as controlling hardware, encoding data, and optimizing calculations.

💼 Career

Understanding bit shifts is important for embedded systems developers, game programmers, and anyone working close to the hardware.

1

Create the initial number

Create an integer variable called number and set it to 8.

C

# Create an integer variable called number and set it to 8
// Your code here

Need a hint?

Use int number = 8; to create the variable.

2

Create shift amount variables

Add two integer variables called left_shift and right_shift. Set left_shift to 2 and right_shift to 1.

C

#include 

int main() {
    int number = 8;
    // Create left_shift and right_shift variables
    // Your code here
    return 0;
}

Need a hint?

Use int left_shift = 2; and int right_shift = 1;.

3

Apply left shift and right shift

Create two integer variables called shifted_left and shifted_right. Set shifted_left to number left shifted by left_shift. Set shifted_right to number right shifted by right_shift.

C

#include 

int main() {
    int number = 8;
    int left_shift = 2;
    int right_shift = 1;
    // Create shifted_left and shifted_right using bit shifts
    // Your code here
    return 0;
}

Need a hint?

Use << for left shift and >> for right shift.

4

Print the results

Print the values of shifted_left and shifted_right using printf. Print shifted_left first, then shifted_right, each on its own line.

C

#include 

int main() {
    int number = 8;
    int left_shift = 2;
    int right_shift = 1;
    int shifted_left = number > right_shift;
    // Print shifted_left and shifted_right
    // Your code here
    return 0;
}

Need a hint?

Use printf("%d\n", shifted_left); and printf("%d\n", shifted_right);.
