Day 2 of C++ Programming: Bitwise Operators (AND, Shift, NOT)

Anurag Parmar — Sun, 21 Sep 2025 08:16:35 +0000

On Day 2 of my C++ journey, I explored bitwise operators.

These are super powerful because they operate directly on binary bits — the true language of the computer.

At first, they look abstract, but once I saw the outputs of small numbers, I understood why they’re so important.

✅ Example 1: Bitwise AND (`&`)


cpp
#include <iostream>
using namespace std;

int main() {
    int x = 11, y = 7, z;
    z = x & y; 
    cout << z << endl;
    return 0;
}
Explanation
11 → 1011 (binary)
7 → 0111 (binary)
1011 & 0111 → 0011 = 3
👉 AND is useful in masking operations (filtering specific bits).

✅ Example 2: Bitwise Shift (<<)
C++

#include <iostream>
using namespace std;

int main() {
    char x = 5, y;
    y = x << 1; // left shift by 1
    cout << (int)y << endl;
    return 0;
}
Explanation
5 → 0101 (binary)
Shift left by 1 → 1010 (binary) = 10
👉 Shifting left is basically multiplying by 2.
✅ Example 3: Bitwise NOT (~)
C++

#include <iostream>
using namespace std;

int main() {
    char x = 5, y;
    y = ~x;
    cout << (int)y << endl;
    return 0;
}
Explanation
5 → 00000101 (binary)
~x flips all bits → 11111010
Result = -6 (in signed integer representation).

Backend

🌐 Diving into Web Development – My First Backend with Node.js & Express 🌐

After learning Python and other languages, tonight I explored Web Development and built my very first backend using Node.js and Express. It’s amazing to see how a few lines of code can make a server respond to requests!

Here’s what my first backend can do:
🔹 Sends Hello World on the home route /
🔹 Responds with my Twitter handle on /twitter
🔹 Shows a simple login message on /login

This small project helped me understand routes, server setup, and basic API handling. Slowly, I’m connecting frontend and backend knowledge to build full-stack applications.

🌙 Evening Coding Log – JavaScript Basics 🌙

After working on Java in the afternoon, I switched gears to JavaScript this evening. JavaScript always excites me because it’s the language that brings web pages to life 🌐⚡.

Here’s what I practiced today:
🔹 Basic arithmetic operations
🔹 Writing and using functions
🔹 Applying if-else conditions
🔹 Playing around with arrays

These small steps are helping me understand how JavaScript handles logic and data differently compared to C++ or Java. I’m slowly connecting the dots between languages while keeping my foundation strong.

👉 Do you remember the first JavaScript code you ever wrote? Share it below ⬇️

As I continue my journey into C++ 🚀, I realized that a strong foundation in C language is equally important to truly understand how things work under the hood.

So, I decided to go back to the basics and practice simple but powerful concepts in C 💻. Here are a few codes I worked on today:

🔹 Printing my first Hello World in C.
🔹 Performing multiple operations (+, −, ×, ÷, true/false).
🔹 Exploring logical operators like && (AND), || (OR).
