This C++ program demonstrates how to print multiple lines of text to the console using the cout statement.

1. Header and namespace

   1. #include <iostream> includes the input/output stream library, which allows the program to use cout for printing text.

   2. using namespace std; lets us use standard library objects (like cout and endl) without writing std:: before them.

2. Main function

   1. The program starts executing from the main() function.

   2. Each cout statement outputs a line of text to the console, followed by << endl; which moves the cursor to the next line.

3. Output lines

   1. cout << "I'm learning C++!" << endl; prints the first message.

   2. cout << "Welcome to the machine." << endl; prints the second message.

   3. cout << "Let's write some code!" << endl; prints the third message.

4. Return statement

   1. return 0; indicates successful program completion.
