🎯 Today I started my TakeUforward+ journey! Currently, I’m diving into C++ Basics — and the very first thing I learned is about #include. Here’s how it starts: #include <iostream> int main() { return 0; } But why do we even need #include? 🤔 👉 Imagine reading a book written in English — you must know English to read it. Similarly, when our program runs, it must know the rules of C++. That’s exactly what iostream provides — rules for input and output. 📌 More examples: For math functions → #include <math.h> For strings → #include <string.h> So, every feature in C++ has its own library of rules that we must include. 💡 Not sure which library to use? ✅ Just Google it — that’s what every programmer does! There’s also a shortcut: #include <bits/stdc++.h> int main() { return 0; } This pulls in all the libraries. Handy for beginners, but ⚠️ it makes compilation a bit slower compared to including only what’s needed. 🔑 Lesson from today’s session: Keep your code clean — include only the libraries you really need. Excited to continue this journey with TakeUforward+ 🚀 👉 Will keep sharing my daily learnings here! #Cplusplus #TakeUforward #CodingJourney #DSA #ProgrammingBasics
