This is the classic first step into programming. Here is how to print "Hello, World!" in Python, C++, and Java, starting with the simplest and moving to the more structured languages.
1. Python
Python is famous for its readability and simplicity. It often requires only a single line of code to accomplish this task.
How it works:
Python is an interpreted language, so you don't need complex setup code for a simple script.
print() is a built-in function that takes whatever you put inside the parentheses (in this case, a string of text) and displays it on the screen.
2. C++
C++ is a powerful, high-performance compiled language. It requires a bit more structure ("boilerplate code") to set up the environment before you can print anything.
3. Java
Java is a heavily structured, object-oriented language designed to run on any device with a Java Virtual Machine (JVM). Because everything in Java must exist inside a "class," it has the most required code just to start.
Important Note: In Java, your file name must exactly match your public class name. You should save this code in a file named HelloWorld.java.
