C++

What is C++, really?

When performance is non-negotiable, you reach for C++. Chrome browser, Photoshop, Microsoft Office, every AAA game engine (Unreal, CryEngine), MySQL — all C++. It is the workhorse of demanding software.

Why learn it in 2026?

C++ developers are rare and well-paid. If you get into game studios, embedded systems, or trading firms, salaries can hit ₹40+ LPA in India. The barrier to entry filters out most people, which is exactly why it pays well.

What it looks like

// Fast vector operations
std::vector<int> nums = {1, 2, 3, 4, 5};

int sum = std::accumulate(
    nums.begin(), nums.end(), 0
);

std::cout << "Total: " << sum;

How to get started with C++ in 5 steps

1. Install C++ Download C++ from the official site or use a package manager like Homebrew (Mac) or apt (Linux).
2. Set up your editor Install VS Code (free) and add the official C++ extension for syntax highlighting and autocomplete.
3. Write Hello World Create a file, write your first 'C++ Hello World' program, and run it from the terminal.
4. Build a small project Pick something tiny — a calculator, a to-do list, a number guessing game. Building beats reading.
5. Join a community Join the official C++ Discord, subreddit, or Stack Overflow tag. Ask questions when stuck.

Should you learn it first?

Honestly, no — not as your first language. C++ is powerful and pays well, but the learning curve will discourage you. Learn Python or JavaScript first, then come back to this.
