Hello World

Hello World! is often the first program written by developers learning a new programming language. It’s a simple exercise that introduces basic syntax and verifies the setup of a programming environment.

The Origin

The tradition of writing a “Hello, World!” program started with Brian Kernighan and Dennis Ritchie in the book The C Programming Language (1978). This example became a universal convention in computer science.

Examples in Popular Languages

Python

print("Hello, World!")

JavaScript

console.log("Hello, World!");

C

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

Java

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

The Hello, World! program remains a timeless exercise, symbolizing the start of a programmer’s journey and the joy of learning a new language. Whether you’re debugging a simple print statement or building complex applications, every developer started with these first few lines of code.
