Intro

Intro

Intro is a core part of C++. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding intro well means you can read other people's C++ code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What intro means in the context of C++
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with intro

// C++: Intro
#include <iostream>

int main() {
  std::cout << "Exploring Intro" << std::endl;
  return 0;
}

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for intro.
