Boilerplate code is the basic structure you write in every C++ program.

Think of it as a template or starting setup — it includes the necessary lines to write and run C++ code successfully.

🧱 Basic C++ Boilerplate Code


#include <iostream>  // Step 1: Header file for input/output
using namespace std; // Step 2: Makes 'cout' and 'cin' easier

int main() {         // Step 3: Program starts from here
    // Your code goes here
    return 0;        // Step 4: Program ends here
}

🔍 Line-by-Line Explanation:

Line What it does
#include <iostream> Adds input/output support (like cin, cout)
using namespace std; Allows you to write cout instead of std::cout
int main() { Entry point of the program – starts execution here
return 0; Tells the system that program ran successfully
// your code Placeholder for your actual logic

✅ Example with Actual Code


#include <iostream>
using namespace std;

int main() {
    cout << "Welcome, Nikhil!";  // Output line
    return 0;
}

🖨️ Output:


Welcome, Nikhil!
