Your First Program

# Your first Python program
print("Hello, World!")

# Variables and basic operations
name = "Alice"
age = 25
print(f"My name is {name} and I'm {age} years old")

# Simple calculation
x = 10
y = 5
result = x + y
print(f"{x} + {y} = {result}")

Python uses simple, readable syntax. The print() function displays text, and f-strings make it easy to include variables in your output.

// Your first JavaScript program
console.log("Hello, World!");

// Variables and basic operations
let name = "Alice";
let age = 25;
console.log(`My name is ${name} and I'm ${age} years old`);

// Simple calculation
let x = 10;
let y = 5;
let result = x + y;
console.log(`${x} + ${y} = ${result}`);

JavaScript uses console.log() to display output. Template literals (backticks) make it easy to include variables in strings.

// Your first Java program
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
        
        // Variables and basic operations
        String name = "Alice";
        int age = 25;
        System.out.println("My name is " + name + " and I'm " + age + " years old");
        
        // Simple calculation
        int x = 10;
        int y = 5;
        int result = x + y;
        System.out.println(x + " + " + y + " = " + result);
    }
}

Java requires a class structure and a main method. System.out.println() displays output, and you need to declare variable types.
